In the numerical control electric machining equipment, the high-speed photoelectric scrambler is often used to isolate the level signal. In the numerical control pulse power supply, a high-speed optical power is used to send the discharge pulse to the driving circuit of the power vMOS tube to form a discharge pulse; the instantaneous value of the detection signal such as the gap voltage is compared with the set threshold signal, and the result is also passed through the high-speed light accident input controller. The analog signal of the gap detection is often processed by a precision linear optical combiner, and the input control microcomputer is used for linear optical isolation schematic diagram (bandwidth>200KHz) using TIL30. The relay is isolated, utilizing the characteristics of the relay coil and the contact being mechanically separated, and the corresponding action of the strong electric power is controlled by the weak current, such as the working control of the medium pump, the processing voltage, the processing current amplitude modulation control, and the like. Reasonable power scheme measures are caused by the interference signal of the power supply control circuit, not only the amplitude is considerable, but also the frequency band is wide. To suppress such wide-band interference, a reasonable AC and DC power supply must be used. In the case of AC power supply, the interference signal of the CNC machining equipment is below 10MH: Therefore, the varistor and the low-pass filter can be used to greatly attenuate the interference signal; and the shielding layer of the isolation transformer and the power transformer eliminates the interference signal below 20KH:. By using these measures, power supply with better anti-interference effect can be obtained. A suitable DC power supply for DC power is important and effective in suppressing interference and noise.
