25KHZ 900W Digital Ultrasonic Cleaner PCB Circuit Board For Ultrasonic Washer Machine

The output of the error amplifier of the driving circuit board of the household ultrasonic dishwasher is compared with the sawtooth wave wave voltage in the comparator, so that a square wave pulse whose pulse width changes with the output voltage of the error amplifier is output at the output end of the comparator. Then send the square wave pulse to one input end of the OR gate, or to the other three input ends of the OR gate, which are respectively trigger, oscillating sawtooth wave wave, and undervoltage locking. Finally, pulse signals with varying pulse width as a function of output voltage are obtained on output transistor A and output transistor B.
