The digital Ultrasonic welding control box generator needs to process and prepare the Functional requirement of metal welding and plastic welding, which requires the power, frequency and stability of the ultrasonic power supply during the preparation process. This paper has designed the corresponding circuit, which mainly uses the PWM signal generated by STM32 to output the high and low level, uses the half bridge driver IR2110 to drive the full bridge to work, and uses the PID control algorithm.
