Abstract

This article analyzes, designs, and tests a reconfigurable phase shift full-bridge (r-PSFB) isolated dc/dc converter well suited for a wide voltage operating range. By controlling the auxiliary switches, a series or parallel connection can be realized on the secondary side of the converter. As a result, the r-PSFB converter can operate in an extremely wide voltage range without compromising the system efficiency. In this article, the characteristics of the r-PSFB converter and its design considerations are discussed in detail. An 11-kW r-PSFB converter prototype with 640-840-V input voltage and 250-1000-V output voltage ranges is developed and tested to validate the analysis and efficiency of the designed converter. A comparative study against a conventional PSFB converter is conducted for benchmark purposes to prove the advantages of the studied r-PSFB converter.
