다층PCB를 이용한 고밀도 On-board DC/DC Converter

Abstract

다층 PCB를 이용한 고밀도 전원을 개발함. In this paper, high density on-board dc/dc converter using multi-layer PCB is proposed. Recently, the communication system wants power supply of open-frame, high density and low profile. So experimental converter was consisted of 33V/30A Quarter Brick size DC/DC Converter. To power height limit, coil of transformer, choke and circuits were consisted of multi layer PCB. Besides to Improve of efficiency. made secondary synchronous rectifier Mosfet driving circuit. So total efficiency could be improved.
