The ultrasonic power generator for metal welding has designed a fully digital controlled power supply system for ultrasonic metal welding machine. The power supply system uses phase-shifting PWM digital amplitude control, amplitude step output, programmable Pre-charge, automatic welding head frequency search and automatic frequency tracking techniques. Practical use has proved that the power supply system can quickly realize automatic frequency tracking, accurate amplitude control, and improve fault protection
