The power generator of ultrasonic plastic welding machine is designed with the main circuit of the power supply, automatic resonance frequency tracking system, and output power control system. The design process of the matching network is introduced in detail. The method of using phase control frequency to control automatic resonance frequency tracking is proposed, and the corresponding circuit structure and working principle are explained
