Abstract

This paper describes a record of the study on a high efficiency and high frequency insulation type converter based on new DAB (Dual Active Bridge) soft switching method aimed for the electric vehicle (EV). This power converter is basically proposed for the 20 kHz soft switching with closed loop control by phase shift control using DSP. For evaluating the practical effectiveness of new DAB method converter, the preceding fabrication using IGBT module and power MOSFET module has been completed and basic operational test, the efficiency measurement, light load test and closed loop control test was obtained. The load test by 4 kW of maximum load has been completed. 95.6 % efficiency at 4 kW was obtained and it corresponds to 16 kW with efficiency of 99 %.
