SERIES TYPE DC/DC CONVERTER

摘要

A series type DC/DC converting device is provided to prevent generation of a reactive power by varying a phase displacement of converters according to the number of converters. A converter part(100) comprises a plurality of full-bridge converters(110~110n). Each full-bridge converter includes four switching devices(111). A transforming part(200) boosts an output power of the converter part. The transforming part comprises a plurality of transformers(210~210n) corresponding to a plurality of full-bridge converters. A primary side of a plurality of transformers is connected to a plurality of full-bridge converters. The primary side of a plurality of transformers is parallel connected. A secondary side of a plurality of transformers is serially connected. A rectifying part(300) includes a bridge rectifier(310). The bridge rectifier includes four diodes(311). A filtering part(400) filters a power rectified by the bridge rectifier.
