The development of electric vehicles power electronics system control comprising of DC-AC inverters and DC-DC converters\r\ntakes a great interest of researchers in the modern industry. A DC-AC inverter supplies the high power electric vehicle motors\r\ntorques of the propulsion systemand utility loads, whereas aDC-DC converter supplies conventional low-power, low-voltage loads.\r\nHowever, the need for high power bidirectional DC-DC converters in future electric vehicles has led to the development of many\r\nnew topologies of DC-DC converters. Nonlinear control of power converters is an active area of research in the fields of power\r\nelectronics. This paper focuses on a fuzzy sliding mode strategy (FSMS) as a control strategy for boost DC-DC converter power\r\nsupply for electric vehicle. The proposed fuzzy controller specifies changes in the control signal based on the surface and the surface\r\nchange knowledge to satisfy the sliding mode stability and attraction conditions. The performances of the proposed fuzzy\r\nsliding controller are compared to those obtained by a classical sliding mode controller. The satisfactory simulation results show\r\nthe efficiency of the proposed control law which reduces the chattering phenomenon. Moreover, the obtained results prove the\r\nrobustness of the proposed control law against variation of the load resistance and the input voltage of the studied converter.
