Ultrasonic power supply [Copy link]

Ultrasonic power supply, which we often call ultrasonic generator, is used to convert the mains electricity ( 220V or 380V , 50 or 60Hz ) into high-frequency AC signal that matches the ultrasonic transducer.

From the perspective of amplifier circuit form, linear amplifier circuit and switching power supply circuit can be used. High-power ultrasonic power supply generally adopts the circuit form of switching power supply from the perspective of conversion efficiency.

Linear power supply also has its unique application range. Its advantage is that it does not strictly require circuit matching and allows the operating frequency to change continuously and quickly.

Judging from the current situation in the ultrasound industry, ultrasound is mainly divided into self-excited and externally excited power sources.

Generally, we call a power supply that can generate an oscillation signal without connecting a transducer an externally excited power supply, and the opposite is called a self-excited power supply.

It would be better if you could write more details! But it is already very good!!!
