The circuit board of the ultrasonic machine adopts the commonly used half bridge independent excitation drive circuit in China, with the front half bridge and rear transformer even driving the ultrasonic cleaning transducer; Inductance and capacitance to match the impedance and capacitance of ultrasonic transducers. The power supply circuit, resonant circuit, and switching circuit better enable the ultrasonic cleaning transducer to work at the resonant point.
