We have an Induction Heater about 30kVA, Consists of(Rectifier, H-Bridge IGBTs (FF300R12KS4) , Capacitor, Transformer, and coil)
The problem is It has no output power when pressing RUN, I have tested all of its power components such as IGBTs and its drivers, capacitor and transformer, there is no any problems for them, but I have noticed that the controlling circuit - which initiates drive as a very low frequeny (about 100Hz) when measuring using multi-meter.
The drivers get signal, but it seems to be protected by (Sat. Voltage). but there is no any Short circuits and the load is a light load.
The question is: can I apply signal for IGBT drivers using micro-controller, also which frequency should I apply?
