Plastic Welder Ultrasonic Generator PVC PP ABS Digital Power Generator For 20KHz-2000W Ultrasonic Welding Machine

The intelligent automatic frequency tracking digital circuit Ultrasonic welding generator power supply is an application of power ultrasonic technology and has been widely used in industrial manufacturing. The Ultrasonic welding power supply is the core component of the Ultrasonic welding system. The power supply first rectifies the mains power to the DC bus, and then outputs the AC voltage through the inverter to drive the transducer to convert the electrical energy into vibration mechanical energy, High frequency vibration is used to complete the welding of plastic or metal parts. To work at the resonance point of the transducer, the power inverter needs to design a matching circuit to offset the redundant reactance so as to improve the output efficiency. Because the resonance point drifts due to temperature changes and other reasons, resulting in increased loss of the transducer and decreased amplitude, the inverter needs to track the resonance point to keep the system working efficiently
