Researches on Combined Input-series Output-parallel Systems Composed of Full-bridge DC Transformers and Converters
摘要
Abstract
High voltage is one of the design difficulties for the DC converters in high voltage direct current (HDVC) systems. Multi-module series and parallel combinations is one of the effective solutions. The composite structure of full-bridge DC transformers and full-bridge DC converters as two kinds of standardized modules was used for a combined input-series output-parallel (ISOP) DC converter where high voltage will be transformed to low voltage. Unlike m the traditional combined ISOP DC converter, a combination of the open-loop and closed-loop control was used in the composite structure. It ensures that the voltage differences of all modules are controlled in a certain range, and will simplify the control method. Based on the analysis of the output characteristics of each module, this paper gave out a voltage-sharing design of the combined ISOP DC converter. An ISOP simulation model and a principle prototype consisting of two full-bridge DC transformers and one phase-shifted full-bridge series resonant converter were built to verify the effectiveness of the proposed design.关键词
