100KHZ 1200W High Frequency Ultrasonic Generator PCB Circuit Board Control Power Supply Generator

The design of a low-power and low-cost ultrasonic generator circuit board is a fully automatic ultrasonic impedance matching system and method for ultrasonic cleaning generators. The system includes a main control circuit, an input current processing circuit, and an acoustic impedance matching signal processing circuit; The input current processing circuit is used to read and rectify the current signal of the mains supply, and send the rectified current signal of the mains supply to the acoustic impedance matching signal processing circuit;

The circuit board design of a low-power and low-cost ultrasonic generator uses an acoustic impedance matching signal processing circuit to read the initial current signal of the resonant output transformer collected by the primary effective current detection circuit, as well as the current signal of the input current processed by the processing circuit. The above two current signals are integrated and compared with the reference voltage, and the comparison results are sent to the main control circuit.

The circuit board design of the low-power and low-cost ultrasonic generator of the present invention is a fully automatic ultrasonic impedance matching system and method, which can perform real-time detection of the acoustic resistance of the ultrasonic system and facilitate the control of the acoustic resistance of the ultrasonic system to be within the matching range at all times.
