Abstract: The increasing demand for more efficient high power supplies have forced to draw attention towards high frequency isolated threephase DCDC converter. Herein, a high frequency isolated threephase DCDC converter was studied, which can be used in the applications that require very low voltage conversion ratio, isolation, good regulation against load and line disturbances, and fast dynamic response. In this paper, modeling, control and design of highfrequency isolated threephase DCDC converter is carried out under asymmetrical control with fixed frequency operation and its steady state analysis is presented according to the description of the operation stages of the converter. A 750 W/5 V/150 A prototype model of proposed DCDC converter is built and tested under different operating conditions. Based on experimental results under the control method, performances of proposed converter have been investigated in view of low voltage high current applications.
