This reference design is a digitally controlled 3.6kW, 54V single-phase AC-to-DC rectifier with all GaN switches. This design is a demonstration for modular hardware system common redundant power supply (M-CRPS) with standard form factor. The input stage chooses a single-phase, totem-pole bridgeless power factor correction (PFC), and the output stage chooses a full-bridge, inductor-inductor-capacitor (FB LLC) converter with full-bridge synchronous rectifier (FB SR). The LLC stage efficiency achieved is 98.5% at the half load, and the PFC stage efficiency achieved is 98.92% at the half load.
