2400W 20KHZ 40KHZ DIY Cleaner Ultrasonic PCB Generator Circuit Board For Cleaning Piezoelectric Transducer

The working principle of the 28KHZ-40KHZ ultrasonic frequency PCB control circuit board adopts a full bridge phase-shifting series resonant circuit, with IGBT as the power switch device, which has low heat consumption, high conversion efficiency, and low noise. Combined with an appropriate type of cleaning tank and cleaning solution, the cleaning effect is good. The ultrasonic power circuit and ultrasonic cleaning equipment, after each pulse width modulation signal passes through the totem pole drive module and switch tube circuit module, The ultrasonic energy conversion module is driven by the transformer module to generate ultrasonic waves, greatly reducing the heat generated in the ultrasonic power supply and extending the lifespan of the circuit

The 28KHZ-40KHZ ultrasonic frequency PCB control circuit board is a frequency tracking system composed of a D trigger, a microcontroller, a digital potentiometer, and a voltage controlled oscillator. The system uses a microcontroller to detect the voltage and phase difference of the ultrasonic cleaning power supply load, and changes the output frequency of the voltage controlled oscillator through a digital potentiometer. Compared with other frequency tracking methods, this system reduces the complexity of programming, and the circuit is simple and easy to implement

The main applications of the 28KHZ-40KHZ ultrasonic frequency PCB control circuit board are digital ultrasonic cleaning machines, small ultrasonic cleaning machines, stainless steel ultrasonic cleaning machines, medical ultrasonic cleaning machines, and so on.
