Abstract

This paper presents a two-stage distributed power system for telecom and server applications. The proposed system has a two-channel interleaved three-phase single-switch boost rectifier with zero-current switching in the power factor correction stage, followed by a three-level zero-voltage and zero-current-switching DC/DC converter. The proposed distributed power system supplies 6 kW and features low cost, reduced size of the input EMI filter, IEC 61000-3-2 Class A harmonic compliance, high efficiency, high reliability and high power density
