hi.. im woking on the design and fabrication of a dc to ac inverter without using a transformer.the design involves first steping up the dc input to a high dc output.this output is switched using a bridge inverter to produce a square wave ac. A voltage has to be provided at the gate of the IGBTs equal to the required voltage across the load.generating this high voltage signal is not difficult,the problem is that the gate break down of common IGBTs voltage is around 30 to 40 volts which is much less than the required 220v!
is there a device which has a gate or base breakdown voltage of 200 or close?
if not, then how do we switch a high dc voltage?
