Abstract

The number of transformers needed in isolated power semiconductor device gate driver circuits can be reduced by using a phase-switched carrier signal technique. This is combined with integrated magnetic techniques to further reduce the number of isolation elements required. A circuit is presented which uses only a single magnetic component to drive both the power semiconductor devices in a bridge leg circuit. Each device is provided with a local floating power supply and can be driven at any duty factor between 0% and 100%. Experimental waveforms are given and implementation is discussed.
