Changwoo Yoon, Sewan Choi, “Multi-Phase DC-DC converters using a Boost Half Bridge Cell for High Voltage and High Power Applications”

Abstract : In this paper multi-phase DC-DC converters are proposed for high voltage and high power applications. A generalized converter is configured such that the BHB cells and voltage doublers are connected in parallel or series to increase the output voltage and/or the output power. In addition to significantly reduced device voltage and current ratings the proposed converter has the following features : significantly reduced transformer turn ratio, ZVS turn-on of switches and ZCS turn-off of diodes, no additional clamping and start-up circuits required, high component availability and easy thermal distribution due to the use of multiple small components, flexibility in device selection resulting in optimized design. A design guideline of determining the optimum circuit configuration for given output voltage and power level is presented. Experimental results are also provided to validate the proposed concept.
