High Frequency Digital Power Ultrasonic Welding Generator For Ultrasonic Plastic Welding Machine

Intelligent digital control ultrasonic welding power supply is an industrial ultrasonic welding power supply with full digital control. The ultrasonic welding power supply adopts ARM embedded processor, multi-task operating system, and has energy, time and peak power control mode. The intelligent digital control ultrasonic welding power supply is made of imported parts and has the best frequency automatic tracking system in the industry.

 

 

 

The main circuit of intelligent digital control ultrasonic welding power supply uses phase-shifting method to control the full-bridge converter. A new automatic tracking method of current RMS deviation frequency is proposed. The intelligent digital control ultrasonic welding power supply also has the functions of automatic resonance frequency point search and storage, programmable slow start, programmable amplitude ladder output control, programmable defective product detection control, RS232/RS485 communication interface based on ModBus protocol, etc.

 

 

 

Intelligent digital control of the frequency tracking design of the ultrasonic welding power supply, so that the ultrasonic transducer can always work at the resonance frequency to ensure the maximum mechanical efficiency output, otherwise, it is easy to occur the detuning phenomenon, and the mechanical vibration efficiency is greatly reduced. So in the design of ultrasonic power supply, how to accurately detect the phase difference and amplitude of ultrasonic welding transducer, and quickly carry out frequency tracking and power control has important practical significance for the research of ultrasonic power supply control system.
