Hello,
The following article on Mosfet gate drive methods is amongst the world’s finest. Why then, does Balogh not mention the method of using an external Gate drive supply SMPS? As you know, this method means having isolated outputs which simply feed a gate drive IC next to the high side FET. A digital isolator couples the gate drive signal to the high side gate driver.
