Multi transformer flyback converter for supplying isolated IGBT and MOSFET drivers
A multi transformer flyback converter topology for supplying transistor drivers is presented. The topology presents some advantages over typical multi output single transformer, as reduction of effective leakage inductance, equal magnetic coupling between primary and secondary circuits and better isolation between outputs. Simulation study carried out in the LTSpice IV program and preliminary experimental results indicate high performance of the six isolated output symmetrical positive and negative dc power supply.
