Abstract
A gate drive power supply (GDPS) system includes a voltage boost stage configured to boost an input voltage into a boost voltage and an inverter stage configured to invert the boost voltage into an AC voltage. The GDPS system further includes gate drive voltage supply circuits transformer coupled to the inverter stage to receive an AC output based on the AC voltage and configured to convert the AC output into DC supply voltages for gate drives.
