TIDA-00199, Wide-Input Isolated IGBT Gate-Drive Fly-Buck Power Supply for Three-Phase Inverters - Reference Design. This reference design provides isolated positive and negative voltage rails required for Insulated Gate Bipolar Transistor (IGBT) gate drivers from a single 24-volt DC input supply. Utilizing a Fly-Buck control topology, this reference design uses a single transformer for generating power rails for all three arms of the 3-phase inverter. It uses primary-side regulation and can achieve good cross regulation without Optocoupler feedback or an auxiliary winding. The isolated outputs are generated through the coupled windings of the transformer
