Abstract

In order to analyze and compare the operating characteristics of high frequency isolated single and three-phase DC-DC converters under the same traditional control method. Firstly, comparisons on single-phase dual active bridge bidirectional DC-DC converter (DAB) and three-phase DAB based on the traditional phase-shifting control were carried out, operating principles of single and three-phase DAB under the traditional phase-shifting control were introduced in detail and analysis on operation modes was provided. Secondly, mathematical models of the transmitted power and backflow power of single and three-phase DAB were built. Through analysis, it is showed that, under same transmitted power, the three-phase DAB has lower backflow power and higher power transmission efficiency. Lastly, simulation models of single and three-phase DAB were built in EMTDC/PSCAD to verify the operating principles and transmitted power of single and three-phase DAB and the relative sizes of their backflow power.
