Description

The STDES-3KWTLCP reference design introduces a complete ST digital power solution for a 3 kW/53.5 V power supply targeting the latest 5G telecom rectifier application.The circuit configuration consists of a front-end AC-DC bridgeless totem pole converter and a back-end DC-DC isolated fullbridge LLC converter. The front-end totem pole converter provides power factor correction (PFC) and total harmonic distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage.This reference design opens the path to a compact solution and offers a high peak efficiency. The measured peak efficiency of the complete PSU at 230 VAC is 96.3%. The overall outline dimensions of the PSU are 105 mm x 281 mm x 41 mm, which yields a power density up to 40 W/inch³.The STDES-3KWTLCP is a fully assembled kit developed for performance evaluation only, not available for sale.This document describes the converter hardware, a summary of the experimental results, and the design recommendations for the complete ST solution.
