Ordinary three-phase 380V/50Hz alternating current is converted into adjustable-voltage pulsating direct current via the rectifier circuit. After filtering, the DC enters the inverter bridge, and then achieves metal heating through resonance in the load tank circuit. The equipment adopts a modular structure, with an oil-immersed step-down transformer at the input, a low-voltage MOS type inverter bridge, and a parallel resonance mode for the tank circuit. It features mature technology, low failure rate, split design for easy on-site placement, good heat dissipation and low cost.
