High-Density 3kW Rack-Mount PSU with Totem-Pole PFC

Webinar Overview

In this brief webinar, presented in Chinese, we will discuss a 3kW rack-mount power supply that achieves 40 watts per square inch power density. The design delivers 97% peak efficiency at high voltage and 96% average efficiency across 100-240 VAC inputs. This high-efficiency solution targets industrial, communications, and server applications while reducing BOM costs and simplifying PFC design implementation.

We will discuss several key innovations, including:

An analog totem-pole PFC controller.
Dual-transformer cycle-by-cycle current detection.
SiC power devices with digital loop compensation.
