Kontrollboksen til ultralydrengjøringsgeneratoren kan forbedre påliteligheten og stabiliteten til kretsen til ultralydrengjøring, og oppnå effekten av enkel krets, Lavpris, small size, and convenient installation. The piezoelectric transducer used for ultrasonic cleaning must work in the resonance state to achieve maximum efficiency. The current common parallel resonance design, while ensuring the resonance frequency, reduces the output power, and cannot achieve maximum efficiency, Although the commonly used full bridge inverter structure has high output power, it has poor stability and is prone to imbalance between bridges.

1. A series matching inductance circuit was developed and matched with the transducer using a series matching method, achieving stable operation of the transducer at the resonant frequency.

2. Through theoretical analysis, it is determined that a half bridge inverter topology structure should be used in the main power circuit. Relevant circuits have been developed, including rectification and filtering circuits, power matching circuits, and signal driving circuits, which ensure that the power output meets the cleaning requirements.

3. Designed circuits and devices for heat dissipation, delay protection, overcurrent protection, buffering protection, and overheating protection,
