This reference design provides reinforced 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 flyback isolated control topology, this reference design provides isolation compliant to IEC61800-5, and generates power rails for all three arms of the 3-phase inverter from a single transformer. The output power is currently set at 2W/IGBT but can be scaled up for higher power IGBTs by changing the transformer design.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
