REF_3K3W_HFHD_PSU is a 3.3 kW high-frequency and high-density PSU for server and datacenter applications. 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.
Summary of Features
97.4% efficiency @98 W/in³
High frequency GaN LLC design (500 kHz)
Fully integrated transformer structure
2-ph interleaved totem-pole SiC AC-DC
Benefits
Infineon solution using GaN, SiC and Si
Highest efficiency and power density
Digital control for both converters
Hold up time extension circuit
Applications
AC-DC power conversion for telecom infrastructure
Data center and AI data center solutions
