As shown in the figure, the input keys 34 to 42 are arranged on the lower part of the display part 30, the UP·DOWN button 41 is arranged on the horizontal right side, so that the number can be displayed when the number is set, and the output current is arranged on the horizontal left side. The display unit 43 and the output voltage display unit 44 . An output switch 33 is arranged on the left side of the input keys 34 to 42 . The UP·DOWN button 41 is a switch used to increase (UP) or decrease (DOWN) the value displayed on the display unit 30. By continuously pressing, the displayed value can be continuously increased or decreased. . The input keys 34 to 42 are composed of a segment switching button 34 , a start/stop button 35 , a setting button 36 , an editing button 37 , a writing button 38 , a function button 39 , a reset button 40 , and a high-speed button 42 . The high-speed button 42 is a button to speed up the UP speed and the DOWN speed of the UP/DOWN button 41 .

As an operation method, for example, when setting the output current value on the display unit 30, press the UP button 41 continuously to increase the displayed value, and when the value exceeds the target value, press the DOWN button 41 once. At this time, press the high-speed button 42 as needed to quickly change the displayed value.

However, in the display unit with the above structure, each switch and button are not configured according to the functional category, so that operation errors are prone to occur. In addition, when the UP·DOWN button 41 is operated, the switch operation of the high-speed button 42 is sometimes required, so there is a problem. There are problems such as slow operation speed when setting values such as output current value.

In particular, when the power supply unit for electroplating is incorrectly set the current value and other values, the finished product will be far from the quality requirements of electroplating. According to the conventional operation panel, numerical value setting errors are likely to occur, and setting operations cannot be quickly performed.

The display unit lamp 301 designates the numerical unit displayed on the digital display unit 300, and is provided with an LED as a backlight inside, and is composed of a membrane switch that makes characters appear when the LED is lit. By pressing the membrane switch, the LED arranged in the membrane switch lights up and the characters float out. Characters printed in advance on each switch, that is, characters that emerge when pressed are A (ampere), %, H (hour), M (minute), and S (second). Therefore, the unit of the numerical value displayed on the digital display unit 300 is clearly known, and numerical value setting errors can be avoided, and numerical value setting can be performed quickly and accurately.

Here, four types of waveform modes as shown in Fig. 3 (a) ~ (d) are enumerated. CC (Constant current)/CV (constant voltage) mode selection key 530 can choose between constant current control mode (CC) and constant voltage control mode (CV).

The group of mode selection keys described above is concentratedly arranged in one area (second area P2).

Fig. 2 shows the wiring of the above-mentioned power supply device for electroplating.

The first power supply unit 71 connected to the commercial power supply 1 is equipped with a first rectifier circuit 21, a first high-frequency inverter 31, and a first PWM signal generator 61, switches between constant current control and constant voltage control, and outputs a plating current from an output terminal 100. . 4 is a high-frequency transformer, and 5 is an output rectifier circuit. The operation panel 9 is connected to a control circuit, and includes a CPU that outputs and stores output waveforms. Among the current waveforms shown in (a), (b), (c), and (d) of FIG. 3 , selected waveform currents are output.

The second power supply device 72 connected to the commercial power supply 1 is equipped with a second rectifier circuit 22, a second high-frequency inverter 32, and a second PWM signal generator 62, switches between constant current control and constant voltage control, and outputs the plating current from the output terminal 100. . Similarly for the second power supply unit 72, a waveform current selected from the current waveforms shown in (a), (b), (c) and (d) of FIG. 3 is output.

The first power supply device 71 and the second power supply device 72 are connected in parallel (parallel). That is, the output from the output rectifying circuit 5 of each power supply device 71, 72 is introduced into the output terminal 100 through the diode, and the outputs of both sides are combined and then output.

This power supply device for electroplating is provided with a rise signal synchronization circuit 6 connected to a first PWM signal generator 61 and a second PWM signal generator 62 . The synchronous line 6 of the rising signal is operated so that the rising time of the output pulses of the first power supply device 71 and the second power supply device are synchronous. Figure 4 shows the output pulse current. Fig. 4 (a) shows that the offset of the rise time of the output pulse of the first power supply device 71 and the second power supply device occurs randomly, and Fig. 4 (b) shows that the offset of the rise time of the output pulse is 0.1 milliseconds or less. This power supply device for electroplating is controlled as shown in FIG. 4( b ) by the operation of the rising signal synchronization circuit 6 so that there is no shift (synchronization) between the rising times of the output pulses on both sides. In this way, by controlling the rise of the outputs of the two parallel-connected power supply devices at the same time, there is no pulse waveform distortion in the synthesized electroplating current. In addition, internal consumption such as loss of circulating current during parallel operation can be eliminated. When the offset is large, the parallel (parallel) composite wave of the output current wave becomes a stepped waveform during rising and falling.
