Description of the invention: [Technical field of invention] - A parameter configuration method for a converter with a shed correction is a change 2 due to the operation of the correction circuit. _ Capacitance recording [Prior technology] In the electronic circuit industry The well-known power factor correction circuit (p〇werFact〇rc_ti〇n, * _ is PFC) is an important circuit for improving the power factor of the input power. Therefore, it is mainly seen in (4) power supply equipment for the charm, or built in various Wei equipment power supply circuit towel; today's common correction circuit includes Wei-style and single-stage, although the two-stage 〇 can provide higher power factor and lower total harmonic distortion (just hann〇nic toortion) However, the single-stage type can provide a simpler circuit and lower cost, so each has its own applicable mode. However, regardless of the power factor correction circuit, its constituent components must include a storage capacitor (often called "bulk". "eapadtor") is used for adjusting energy; and the single-stage power factor correction circuit is taken as an example. The schematic circuit structure can be referred to the Republic of China Patent Bulletin No. 561675 "Repair of the vibration-reducing circuit Circuit, wherein the diagram of the previous case is the most basic power correction circuit architecture, consisting of an inductor (10), a diode (10), a capacitor (109), and a switch (106), wherein The capacitor (1〇9) is a commonly known storage capacitor in the power factor correction circuit (bulk capacitor: ^ - wheeled circuit • (101) sends a fluctuating DC power, when the switch (106) is turned on The power of the fluctuating DC power is stored in the capacitor (109), and the capacitor (1〇9) releases power to a load output terminal (105). The inductor (1〇6) is turned off when the inductor (1〇) 7) transmitting power to the capacitor (109), in such an operation mode, generating modulated power to the load output terminal (105), the work principle of the power correction circuit being a general knowledge in the technical field However, in order to achieve the "IEC 1000-3-2" standard, the above-mentioned power supply is low in the bus voltage Vbus (bus voltage, that is, the voltage on the path of the main transmission power). (low frequency ripple) must be small In order to achieve a higher power factor, the above-mentioned bus voltage Vbus must be increased. Therefore, in the prior art, only the use of an electrolytic capacitor can achieve the above purpose, and thus an electrolytic capacitor is generally used in the power factor correction circuit. In order to improve the utilization rate of the iron core in the transformer and the stability of the single loop control, the power factor correction circuit operates in a discontinuous current mode (DCM). However, the above electrolytic capacitor has a short life. The life of a solid electrolytic capacitor is estimated to be only a few thousand hours of life at 1 〇 5 art, while the liquid electrolytic capacitor is lower. Therefore, when an electrolytic capacitor is used as a storage capacitor for a power correction circuit, the life of the electrolytic capacitor will be The service life of the illuminating diode is directly limited, and the driving circuit of the illuminating diode is taken as an example. Since the illuminating diode itself has at least 100,000 hours of life, due to the attenuation of the storage capacitor, Because the correction circuit can not work for thousands of hours (the average life of the storage capacitor), at this time, the electricity of the shed correction circuit is laid. The light-emitting diodes on which the board money is soldered must be - and replaced, so that the light-emitting diodes must be discarded along with the entire circuit board when they are half their life, resulting in additional waste and cost increase; From the above example, I know the problem that the life record of the known side correction circuit must be solved. [Description of the Invention] Since the power of the converter is limited by the storage capacitor life, the green of the conversion circuit is configured to pass the various functions in the conversion circuit, and the power factor is not changed. Chen can capacitor life, and thus extend the life of the converter to convert the right /, the force factor correction of the converter component parameter configuration method, wherein the converter has - power factor correction circuit will be - input power, converter has more - The changer converts the modulated power to form an output power =,: The method of the present invention includes: a "capacitor configuration step", a difficult power picking step, and a 201035716 - a verification step 4 Determining the __ test voltage and a voltage lower than the test bus voltage, and according to the parameter of the test mosquito-capacitor capacitance, and taking the ship's capacitance to provide the rated bus voltage in the conversion wiper ^ the energy storage inductor configuration step贱Selecting the inductance value of the secondary-side coil of the transformer, and determining a fault-energy inductor with the power-operated coil of the non-continuous electrical hybrid, so that the converter corrects the electrical material (Iv) the money (di_tin_ cu_ DCM), final verify the power factor correction circuit is configured so that the power factor is too exceed • 〇.9. The converter utilizes a storage capacitor that can be adapted to the test voltage to supply a rated bus voltage lower than the test voltage, thereby causing less power to the capacitive capacitor, and the operation of the converter is limited to The continuous current mode allows the designer to select the electric cell component with a small capacitance value as the storage capacitor. In particular, the designer can select (4) the film capacitor to replace the electrolytic capacitor of the conventional circuit phase, and the effect of further step-by-step is Extending the life of the storage capacitor, and also limiting the life of the converter to the storage capacitor. In summary, in this case, a smaller capacitive component can be used as the storage capacitor, and a thin film capacitor can be further used to extend the life of the power correction circuit. [Embodiment] The present invention is a component parameter configuration method of a converter with power factor correction. Please refer to FIG. 1. As shown in the figure, the converter has at least one power factor correction circuit 3 and - transformer 4, The positive circuit 3 is modulated in a non-continuous f-stream mode - the input power forms a constant-current modulated power, and the modulated power-formed-output power 7 is converted to a load by the transformer-to-transformer 4. The circuit structure of the converter may further include a rectifying circuit 2 for connecting the power source 1 to obtain the input power, and a wheeling unit 7〇5 connected to the secondary side coil of the responsive 4, wherein the rectifying circuit 2 After the input power is obtained, the input power is converted into a fluctuating direct current, and the fluctuated input power is sent to the force correction circuit 3 connected to the rear end of the rectifier circuit 2. The input power is converted into the modulated power by the power factor correction circuit 3, and then passed through the transformer 4' and the induction power of the secondary side of the transformer 4 is obtained by the output unit 5 through transmission, filtering, or impedance matching. The output power 7 is provided by the circuit to drive the load. The type and operation mode of the rectifier circuit 2 and the output unit 5 are well known in the industry, and are not the focus of the present application, and therefore will not be described again. The power factor correction circuit 3 includes a storage capacitor 32, a storage inductor 3, a switching element 33, and a control unit 6 for controlling the opening and closing period of the compensation component 33, wherein the switch 7C determines the power of the hybrid. The direction of the saki, the charge and discharge cycle of the mosquito-like capacitance. Moreover, the variable (4) 4 - the secondary side coil also needs to use - the switch determines the power transmitted to the secondary side coil, and in the circuit diagram of the present case, the switching element 33 of the power factor correction circuit 3 can also be controlled The power transmitted by the transformer 4 is a well-known technique in which the correction circuit 3 and the transformer 4 share the switching element 33. Therefore, the operation of the present invention will not be explained in detail in this case. The parameters of __容32 and _31 are extremely significant for the power factor. Therefore, the method of configuring these component parameters is proposed in the present case, wherein the method includes several steps. Step storage capacitor configuration step, the step is pre-set - test voltage and - rated bus voltage below the service voltage, and according to the test voltage determines the parameters of the ship capacitor 32 (as shown in Figure 2 - _ And applying the storage capacitor 32 to provide the rated bus voltage. Step 2: a storage inductor configuration step, selecting the number of windings of the secondary side coil of the transformer 4, and determining a storage inductor 31 with the same The inductance value of the side coil in the non-continuous current mode (flow 2, 200 shown in Figure 2). Step 2. One verification step, the output unit 5 is configured according to the rated output specification (flow 3 shown in Figure 2) 300), and verify whether the power factor of the converter operation is greater than 〇9 (flow 400 of Figure 4 shown in Figure 2); if not, return to step 1 to adjust the parameter of the storage capacitor %. If the converter is verified If the power factor of the operation is greater than 〇9, then continue to configure other circuit units according to the safety regulations or customer requirements (as shown in Figure 5, process 5:5), the other electrical elements described herein, such as circuit, illuminating And side, grounding lines, etc. The other circuit units described in the process of Figure 5 are the techniques known to the converter (or power supply) manufacturer, and will not be described again. 201035716 In the conventional process of the converter, the designer pre-sets The bus voltage of the front of the power factor correction circuit 3 (generally the common rated bus voltage is 380V), and the conventional energy storage component with the withstand voltage value of the busbar is configured to output the conventional energy storage component. The modulated power can be stably reached to the set bus voltage. Here, the bus voltage system must be defined again, and the power amplifier correction circuit 3 outputs the average voltage of the modulated power to be boosted to the bus voltage.准. 'i The steps of this case - grading - higher than the rated bus voltage test, and according to the voltage value of the 2 test voltage to determine the parameters of the storage capacitor 32, the storage capacitor through the test voltage 32 is further applied to the converter, the side control unit 6 switches the operation of the switch S member 33 to charge the capacitor 32 and output the modulated power reaching the bus voltage. Since the step is higher The test voltage determines the storage capacitor 32. Therefore, the modulated power outputted by the storage capacitor 32 is somewhat microwaved, and the storage capacitor 32 absorbs less input power fluctuations. Therefore, a capacitor with a small capacitance can be selected. As the storage capacitor 32», the inductance of the storage inductor 31 is set in step 2 to match the number of turns of the primary side of the transformer 4, and the power correction circuit 3 operates in a discontinuous current mode, wherein the energy storage The inductance of the inductor 31 determines the current fluctuation speed passing through the energy storage inductor 31, and the number of windings of the primary side coil of the transformer 4 also affects the speed Q of the current rise and fall. Therefore, the transformer 4 is selected first. The number of turns of the side coils is selected to operate in a discontinuous current mode to select the inductance of the energy storage inductor 31 (ie, flow 200 in Figure 2). At this time, please refer to FIG. 1 and FIG. 4 first. FIG. 4 is a waveform diagram of each electrical node in FIG. 1. The electric current and current it represent the current of the primary side and the secondary side coil of the transformer 4, respectively. That is, the process of power transmission on the primary side and the secondary side of the transformer 4, and it is particularly pointed out that the current iib is the current flowing through the energy storage inductor 31. The current ilb must fall after rising in each complete duty cycle. After the zero is reached, the next cycle will start again, and the demand for working in the discontinuous current mode will be met. After the primary side coil of the transformer 4 is selected, the secondary side coil of the transformer 4 is determined in consideration of the transformation ratio of the transformer 4. The second 201035716 secondary side coil of the transformer 4 is connected to the necessary output unit 5 to further provide stable Output power 7. However, the configuration of the power factor correction circuit 3 needs to be verified to determine whether the power factor of the converter is greater than 0.9, and if not, return to step 1 to re-determine the parameters of the storage capacitor 32; if the power factor of the converter is greater than 0.9 Other circuit units can continue to be configured (Scheme 5, 500 as described in Figure 2). In the above configuration method, an additional step can be inserted to make the design of the converter more perfect. The above steps may further include a bus voltage verification step, which is selected after the subsequent step one. After the storage capacitor 32, it is determined whether the modulated power voltage output by the storage capacitor 32 is higher than the input power voltage. If yes, proceed to step 2; if not, return to step 1 to re-determine the appropriate storage capacitor 32 ^ and step 2 further includes a control loop design step, the control loop design step is designed to provide an improved low frequency The gain means is for suppressing the low frequency component outputted by the power factor correcting circuit 3. The implementation flow of the above steps is as shown in FIG. 3, wherein the process 1) determines the parameter of the storage capacitor 32 and then continues an additional step 1〇1 To verify whether the bus voltage of the stored energy supply is higher than the voltage of the input power, if not higher than the input power voltage, return to the pre-step to re-determine the parameters of the capacitor 32; the wire bus voltage is higher than The voltage of the input power is determined by the parameters of the energy storage inductor 31, the number of windings on the primary side and the secondary side of the transformer 4, and the flow of configuring the output unit. _3 3GG after the 嶋, two: circuit 6, and the control (four) road 6 to improve the deportation, the final job identification is greater than 〇.9 (Figure 4 in Figure 4 400), and according to the verification results and return Go to Step 1 or continue to configure other circuit units (Figure 5, Process 5, Figure 5). After the components of the positive circuit 3 are subjected to the above method, the parameters of the storage capacitor 32 are determined according to the test voltage, and the test voltage is higher than the set bus = the modulation generated by the positive circuit 3 The waveform diagram of power and wheeled power can be seen in Figure 5, which represents the input power. It is obvious in this figure that the input power is 201035716 AC, and the output is output after entering the power factor correction circuit 3 through the rectifier circuit 2. The variable power can be seen in Vcb in FIG. 5, and the average value of the modulated power reaches the bus voltage (Vcb_ave) 'The bus voltage must be higher than the voltage of the input power. Wherein, since the first step is to determine the storage capacitor 32 through a higher test voltage, the modulated power output by the storage capacitor 32 has a slight axis, which means that the energy capacitor 32 absorbs less input power waves. 'Therefore, it is possible to record a small capacitive element _ aero-capacitor 32. In particular, the designer can reduce the thinning capacity to replace the conventional (four) electrolytic capacitors, and the effect of further step-by-step is to extend the life of the current capacitor & _ also makes the conversion (four) life not limited by the storage. Capacitor 32.
