REF_3K3W_HFHD_PSU
综述
500 kHz high density 3 kW GaN rectifier for server and telecom applications
REF_3K3W_HFHD_PSU is a 3.3 kW, 95 W/in³ power supply for server and telecom using GaN, SiC and Si devices. The front-end AC-DC converter is a two-phase SiC interleaved bridgeless totem-pole stage for power factor correction, while the high-frequency (500 kHz) DC-DC converter to provide isolation and regulate output voltage is a GaN LLC half-bridge, with full-bridge rectification. The PSU includes a baby-boost stage to hold-up time requirements.
