Digital frequency tracking technology, makes the IGBT always work in zero state, inverter power factor always stay above 95%, the composite structure of motherboard make whole inverter unit without absorbing circuit, inverter efficiency is greatly increased 。

The main advantages of induction heating are: no overall heating, small deformation and small energy consumption.No harm, no harm.The heating speed is fast and the surface of the workpiece is oxidized and decarburized.The surface hardening layer can be adjusted according to need and easy to control.
