REF_1KW_PSU_5G_SIC

Overview

12 V/1kW fan-less SiC-based PSU for outdoor 5G Edge Computing

The PSU comprises a front-end AC-DC bridgeless totem-pole PFC converter followed by a back-end DC-DC isolated half-bridge (HB) LLC converter. The front-end converter provides power factor correction (PFC) and control of the total harmonic distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage at 12 VDC

Summary of Features
