Ultrasonic power supply

Ultrasonic power supply is usually called ultrasonic generating source, ultrasonic generator. Its role is to convert electrical energy into a high-frequency alternating current signal that matches the ultrasonic transducer. From the form of amplifying circuits, linear amplifying circuits and switching power supply circuits can be used, and high-power ultrasonic power supplies generally adopt the circuit form of switching power supplies in terms of conversion efficiency. Linear power supply also has its unique application range. Its advantage is that it does not require strict circuit matching, allowing continuous and rapid change of operating frequency. From the current situation of the ultrasound industry, ultrasound is mainly divided into self-excited and other-excited power supplies.
