This article discusses the principle and circuit composition of 20khzpwm (pulse width modulation). The PWM signal is generated by an integrated circuit with excellent performance. The high -frequency inverter uses international advanced magnetic materials and IGBT power devices. The inverter sends the output high -frequency voltage into the ultrasonic converter to radiate the ultrasonic. The system has the characteristics of simple circuits, reliable work, small volume, low cost, convenient output power adjustment, high efficiency, and strong practicality.
