Poster Presentation: GaN-Based 5 kW Four-Level Totem-Pole PFC Converter for AI Servers Power Supply
Speaker: Marco Palma
Presenting a compact flying capacitor multilevel (FCML) totem-pole bridgeless power-factor correction (PFC) rectifier for the high-efficiency and high-density switching power supplies of AI Servers. It is based on a 5 kW four-level FCML totem-pole PFC employing 200 V GaN devices. The PFC is designed to follow the latest Open Compute Project (OCP) guidelines.

5 kW Isolated 400 V to 50 V, DC-DC Converter for Server Power Supplies
Speaker: Michael de Rooij
The increasing power demand in data centers is driving the need for converters with higher power density and efficiency. This paper presents a solution for the isolation stage in a sever-rack power supply, that complies with the Open Compute ORv3 specification [1]. The solution comprises four LLC converters with stacked primaries and paralleled secondaries, between the 400 V input and 50 V output. Two transformer alternatives are presented to achieve highest peak efficiency (~98.5 %) or highest full load efficiency (~98 %). The converter can continuously process 5.5 kW and fits in a 80 x 70 x 27 mm volume, realizing a power density of 596 W/in3 (36.4 W/cm3).
