The principle of ultrasonic generator is introduced
Ultrasonic generator, also known as ultrasonic driving power supply,
electronic box and ultrasonic controller, is an important part of
high-power ultrasonic system. The function of ultrasonic generator is to
convert the municipal power into high frequency AC signal matched with
ultrasonic transducer, and drive the ultrasonic transducer to work.
Considering the conversion efficiency of high-power ultrasonic power
supply, the circuit form of switching power supply is generally adopted.
Ultrasonic power supply is divided into self excitation power supply
and other excitation power supply. Self excitation power supply is
called ultrasonic simulation power supply, and other excitation power
supply is called ultrasonic generator.
The ultrasonic generator adopts the world's leading other excitation
oscillation circuit structure, and its output power is increased by more
than 10% compared with the self-excited oscillation circuit structure.
Linear amplifier circuit and switching power supply circuit are used in
ultrasonic amplification circuit.
Advantages of switching power supply circuit: high conversion
efficiency, so high-power ultrasonic power supply adopts this form.
Advantages of linear power supply circuit: it does not strictly require
circuit matching and allows continuous and rapid change of working
