| 摘 要： | 为了分析比较在同一传统控制方法下高频隔离单相DC-DC变换器和高频隔离三相DC-DC变换器的运行特性,首先对基于传统移相控制的单相双主动桥式DC-DC变换器(DAB)和三相DAB进行了比较,详细介绍传统移相控制下单相DAB与三相DAB的工作原理,给出工作模式分析;其次,建立单相DAB与三相DAB传输功率以及回流功率的数学模型,经分析可知在传输功率相同的情况下,三相DAB回流功率更小,功率传输效率更高.

| Abstract: | In order to analyze and compare the operating characteristics of high frequency isolated single-phase and three-phase DC-DC converters under the same traditional control method,firstly,the single-phase dual active bridge bidirectional DC-DC converter (DAB) and three-phase DAB based on the traditional phase-shifting control were compared,operating principles of single and three-phase DABs under the traditional phase-shifting control were introduced in detail and analysis on operation modes was provided.Secondly,the mathematical models of the transmitted power and backflow power of single and three-phase DABs were built.The analysis shows that under same transmitted power,the three-phase DAB has lower backflow power and higher power transmission efficiency. |

| Keywords: | phase-shifting control single-phase DAB three-phase DAB transmission power backflow power |
