28KHZ 1500W Ultrasonic Cleaning Generator PCB Circuit For Industrial Ultrasonic Cleaning Machine

The power board of the low-power ultrasonic switch circuit adopts a microcontroller system, which has overcurrent, overheating, and overvoltage protection functions, high reliability, and can track the resonance frequency changes of the ultrasonic cleaning transducer in real-time, with stable output power. At present, the low-power ultrasonic switch circuit power board has been successfully operated and has achieved good results in use.

The power board of the low-power ultrasonic switch circuit is mainly composed of two parts: the main circuit and the control circuit. The main circuit of the low-power ultrasonic switch circuit power board adopts an AC-DC-AC structure. The single-phase AC power is rectified and filtered to form DC power, which is converted into AC voltage with a frequency consistent with the resonant frequency of the ultrasonic cleaning transducer through a full bridge inverter. The inverter outputs AC current, which is then matched through a matching network, Send to the load transducer. The power board control circuit of the low-power ultrasonic switch circuit mainly provides switch pulse signals for the inverter main circuit, drives the inverter main circuit to work, and achieves closed-loop control of the inverter with the help of feedback loops and given circuits.

A digital ultrasonic power supply with stable performance, simple control and adjustment, and low cost has been developed by combining a single-chip microcomputer with an analog integrated circuit to form an intelligent control system for a low-power ultrasonic switch circuit power board.
