Description

Damping charging device

The invention relates to a damping charging device capable of converting a DC-free continuous power without frequency response into a frequency-responsive electric energy and charging the battery to accelerate the charging speed, and during the charging process, there is no consumption of electric energy.

1 shows a conventional charging device 11 which can be connected to the power generating device 10 at one end and to the capacitor battery 12 at the other end. With the charging device 1, the electric energy output from the electric energy generating device 10 can be charged into the capacitor battery 12. The capacitor battery 12 can release power for the load 13 to work. The electric energy generating device 10 may be a regenerative energy generating device or a power supply device.

The conventional charging device 11 includes a transformer 14, a control circuit 15, and a rectifying diode 16. The transformer 14 is capable of raising or lowering the voltage output from the electric energy generating device 10. The control circuit 15 mainly controls the transmitted power to be a constant current and a constant voltage. The rectifying diode 16 is capable of rectifying the transmitted power into a DC type having no frequency response.

The transformer 14 in Fig. 1 is a voltage regulating output of the electric energy outputted by the electric energy generating device, and can be regarded as a power supply, and the internal resistance is r. The capacitor cell 12 can be considered as a load relative to the transformer 14 which produces an impedance R during charging. During the charging process, the power is charged into the capacitor battery in a voltage state to increase the potential level of the capacitor battery 12. Therefore, the charging battery 12 generates heat during the charging process. The transformer 14 outputs a continuous power pair The capacitor battery 12 is charged for work and is bound to face maximum power transfer (MPTT). When the impedance R of the capacitor battery 12 is the same as the internal impedance r of the power transmission path of the transformer 14, the electric power is the maximum output, that is, Poutmax = 1/2 Pin. Therefore, more than half of the power is consumed in the circuit, and it falls into a dilemma where the charging efficiency is too low.

FIG. 1 shows a conventional charging device 11 that charges a capacitor for a long time due to a capacitive anti-law force (reacting an electrostatic force that changes across the voltage across the capacitor). Further, when the transformer 14 outputs electric power of a large current, the capacitor battery 12 is burnt and the charging operation cannot be completed.

The present invention is primarily directed to providing a damped charging device that can be quickly charged without the problem of maximum power transfer.

In order to achieve the above object, the present invention must discard the conventional method of increasing the potential level of the capacitor battery, and convert the power into a frequency-responsive electric energy and then charge it into the capacitor battery.

The damper charging device disclosed by the present invention comprises: a power output device, a control circuit, a damper inductor, and a high frequency oscillating switch. The power output device is connectable to the power generating device. A capacitor battery to be charged by the charging device has a positive terminal connected to the damper inductor and a negative terminal connected to the high frequency oscillating switch.

The power output device can output a power source by boosting or stepping down the power output by the power generating device. The control circuit is capable of regulating the power outputted by the power output device in a state of constant current and constant voltage. The damping inductor comprises a silicon steel core, an amorphous core, and a coil. The inductance value of the silicon steel core will follow the frequency The rate increases with an increase; the inductance value of the amorphous enamel core decreases as the frequency increases. By virtue of the operation of the high-frequency oscillation switch, the damping inductor acts as a high-frequency storage and discharge to offset the capacitive anti-fader force. The damper inductor is capable of discharging electrical energy having a frequency response to charge the capacitor battery.

The power output device may be a transformer or a power supply.

The high frequency oscillation switch may be a fast diode having a fast gate characteristic.

The electric energy generating device may be a regenerative energy generating device or a household power source.

Please refer to Figure 2 and Figure 3. The damper charging device 1 disclosed in the present invention comprises: a power output device 20, a control circuit 30, a damping inductor 40, and a high frequency oscillation Off 50. The power output device 20 can be connected to an electric energy generating device 10, which mainly boosts or depressurizes the electric energy output from the electric energy generating device 10 and outputs the power. The capacitor battery 12 to be charged by the damper charging device 1 has its positive terminal connected to the damper inductor 40 and the negative terminal connected to the high frequency oscillating 50 switch. The electric energy generating device 10 may be a regenerative energy generating device or a household power source.

The control circuit 30 is electrically connected to the power output device, and the current is stably transmitted under a state in which the power output from the power output device is regulated at a constant current and a constant voltage. The control circuit 30 is a conventional technique.

The damping inductance is electrically connected to the control circuit. See Figure 5 and Figure 6. The damper inductor 40 includes a silicon steel core 41, an amorphous enamel core 42, and a coil 43. The silicon steel core 41 and the amorphous core 42 are placed against each other, and the coil 43 is simultaneously wound around the silicon steel core 41 and the amorphous core 42. The inductance value of the silicon steel core 41 increases as the frequency increases. The inductance value of the amorphous enamel core 42 decreases as the frequency increases. When the current passes through the damper inductor 40, its inductance will generate self-oscillation to offset the anti-law force of the capacitive load (the larger the capacity of the capacitor battery, the greater the anti-fader force). Without increasing the temperature of the damping inductor 40, naturally no energy consumption is caused. In Fig. 5, the silicon steel core 41 and the amorphous core 42 are rod-shaped. In FIG. 6, the silicon steel core 41 and the amorphous core 42 are both annular.

By the operation of the high-frequency oscillation switch 50, the damper inductor 40 is continuously operated for high-frequency storage and discharge. When the high frequency oscillation switch 50 is in the ON state, the damping inductance 40 stores electric energy. When the high frequency oscillation switch 50 is in the OFF state, the damping inductor 40 releases the stored electrical energy to charge the capacitor battery 12. Released by the damping inductor 40 It is electrical energy with a frequency response. Therefore, the damper charging device 1 of the present invention charges the electric energy having the frequency response into the capacitor battery 12, and the conventionally-discharged continuous power without frequency response is charged into the capacitor battery 12 to improve the capacitor battery. The 12 potentials are different.

The damper charging device 1 of the present invention charges electric energy having a frequency response into the capacitor battery 12, and naturally, the capacitor battery 12 is easily charged, and the charging speed can be accelerated. Since the anti-fader force is eliminated, the charging frequency can be raised to the limit without causing a problem of temperature rise of the capacitor battery 12.

The power output device 20 may be a transformer 21 that can boost or depress the power output from the power generating device 10 and output the power. The power output device can be a power supply to directly output power. Referring to FIG. 4, the high frequency oscillation switch 50 can be a fast diode 51 having a fast gate characteristic, such as a Schottky diode, which can reach the limit of frequency.

The damper charging device 1 shown in FIG. 2 to FIG. 4 mainly charges the capacitor battery 12 . The capacitor battery 12 itself has a capacitive characteristic and can generate a damping effect of the buffer. If the damper charging device 1 mainly charges the secondary battery, the secondary battery is burnt due to the excessive frequency of the electric energy. 7 and 8 show another embodiment of the present invention. The damper charging device 2 includes a power output device 20, a control circuit 30, a damper inductor 40, and a high frequency oscillating switch 50, and further includes a super capacitor 60 provided with a large capacity. The super capacitor 60 is connected in series with the damping inductor 40, and forms a damper with the damping inductor 40. The secondary battery is charged 17 by the damping effect of the super capacitor 60.

During the storage and discharge of the damper inductor 40, the inductance will generate self-oscillation, without increasing the temperature of the inductor, and naturally no energy consumption will be caused. Charging type of the invention The state in which the damper inductor 40 releases the frequency-reactive electric energy (electron flow) is charged into the capacitor battery 12, so there is no problem of maximum power shift (MPTT, ie, Poutmax=1/2 Pin). In addition to the slight consumption of current transfer in the circuit, the damper charging device 1 of the present invention can charge all of the electrical energy into the capacitive battery 12. The charging method of the present invention is to charge the frequency-responsive electric energy (electron flow) into the capacitor battery, which is different from the potential level of the lifting capacitor battery 12 in FIG. 1, so that the capacitor battery 12 can be quickly charged. There will be no warming.

The above description of the present invention is intended to be illustrative of the preferred embodiments of the invention. Anyone familiar with such art can understand, and appropriate changes and adjustments will not lose the essence of the present invention, without departing from the spirit and scope of the present invention.
