This reference design is a compact, dual-channel output isolated gate driver board design for insulated-gate bipolar transistor (IGBT) in solar inverter, PCS, UPS and motor driver applications. The isolated bias power is implemented with fly-buck topology using TPS54308 which offers two-channel isolated outputs with 1500-V isolation while achieving good voltage regulation. The design is a single-layer PCB board for easy manufacturing.
