Abstract :
Energy savings continues to build momentum on a global scale. The telecommunication industry has responded with high efficiency DC power systems to reduce energy consumption. This paper explores the design considerations of high efficiency (96%) telecom rectifiers in concert with high power density requirements (34W/inch3). Specifically, the design considerations of a high efficiency, high density bridgeless PFC stage followed by a LLC DC-to-DC stage is explained. Experimental results are presented to validate the design approach.
