Supply & Demand

The 3rd Generation SIC-MOS Solid State H.F. Welder utilizes high-power SIC-MOS components from IVCT Company to form the inverter circuit, saving 15%~25% of power compared to traditional solid-state high-frequency welders. With an integrated design, it features a more compact structure, simpler maintenance, and easier scalability to high power. It incorporates unique bridge current-sharing protection technology to ensure the safety of solid-state high-frequency welder operation. By integrating advanced control concepts from international counterparts, the equipment achieves more stable operation and higher efficiency.

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.
