Fuzzy Logic Control Based MIMO DC-DC Boost Converter for Electric Vehicle Application

Nowadays the usages of electric vehicles are increased than the fossil fuel vehicles. In the case of electric vehicle which using dc motor has at least two different voltage levels one for ventilation system and cabin lightening and other for supplying electric motor. Here a fuzzy logic based multi input multi output (MIMO) DC-DC boost converter for electric vehicle application is presented, and is compared with the PI based hardware. In this converter the load power can be flexibly distributed between the input sources. The proposed converter has only one inductor with different inputs and outputs. The charging and discharging of energy storages by other input sources can be controlled properly. Depending on the charging and discharging state of the energy storage system two power operating modes are defined for the converter. The validity of the converter and its performance are verified by simulation by using MATLAB/SIMULINK and the results also presented.
