dear friends im trying to drive the H-bridge with a ferrite transformer.but all the ways i tried i couldnt reach the answer.i tried on totem pole and other ways butplz help me how to drive and protect my mega mosfets
Your "mega" mosfets MUST be driven with the correct mosfet driver. If not I can guarantee that they will be destroyed.
The driver must be able to supply 2 -3A into the gate to be able to quickly charge and discharge the gate-source capacitance. There are many integrated single, dual, high-side, low-side, full and half bridge driver I.C.s available. Go to the website of a semiconductor manufacturer and look at their products and application notes. Start with International Rectifier www.irf.com
