An Efficiency Optimization Control Method for Three-Phase Interleaved DC-DC Converter
Because of the environmental friendliness of electric vehicles, research on electric vehicles has become a hot spot in recent years. How to charge electric vehicles faster is critical to the widespread use of electric vehicles. Electric vehicle integrated power unit can use bidirectional DC-DC converter for driving to achieve integrated charging. In order to improve the power density and efficiency of the integrated system, the bidirectional DC-DC for electric vehicle driving uses three-phase interleaved parallel technology. This paper proposes a method to select different interleaved phase numbers according to different output powers of the converter to improve the working efficiency of three-phase interleaved parallel DC-DC converters. This method improves the efficiency of the three-phase interleaved parallel converter under light load and widens the high-efficiency working area of the converter. Finally, simulations and experimental results are conducted to validate the efficiency of the design.
