17KHZ 40KHZ 200W 3000W Ultrasonic PCB Generator Driver As Industrial Cleaning Machine Ultrasonic Generator

Ultrasonic power is often referred to as an ultrasonic source, an ultrasonic generator. Its function is to convert electrical energy into a high frequency alternating current signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and the high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own range of applications. It has the advantage of not requiring strict circuit matching and allowing continuous and rapid changes in operating frequency. From the current situation in the ultrasound industry, ultrasound is mainly divided into self-excited and its exciting power supply.
