The ultrasonic cleaning power supply is divided into self excitation power supply and other excitation power supply according to the design. The self-excited circuit has no signal source. It integrates oscillation, power amplifier, output transformer and transducer to form a closed loop loop. The loop satisfies the amplitude and phase feedback conditions to form an oscillator with power amplification. And resonates on the mechanical resonance frequency of the transducer. The circuit of separate excitation mode is composed of two parts, namely the signal source part and the signal amplification part. The signal source part uses the signal generation and control part with CPU as the core to generate square wave signal for signal amplification circuit; The signal amplification part amplifies the signal generated by the signal source and outputs it to the ultrasonic transducer. The difference of output circuit and voltage of ultrasonic power supply with different circuits is an important reason for the high and low transmission efficiency. At present, the mainstream ultrasonic power supply in the market only samples the power frequency current and cannot accurately control the ultrasonic output power; The ultrasonic frequency is output at a fixed frequency or sweeps with a given frequency bandwidth. In this form, the power frequency will not change with the change of transducer parameters. The mainstream ultrasonic generators have no communication function and cannot be used as components in integrated systems.
