Abstract: This paper presents the design, analysis and implementation of a proposed combined three phase induction motor and its drive system to meet the demand of low-voltage electrical system for hybrid and electric cars, avoiding the high voltage human risks, expensive and complex requirements of the higher voltage insulation and power electronic devices. Development of Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) will offer many new opportunities and challenges to the power electronics industry, especially in the development of the main traction motor drive. Cascade H-bridge (CHB) multilevel inverter with minimum output harmonics for electric/hybrid electric vehicle applications is proposed in this paper. Switching angles of switch devices are determined by selective harmonic elimination technique. So, the effect of low order harmonics are reduced, as a result the efficiency of system has improved. Moreover, the number of DC voltage sources that used in the proposed inverter is less than conventional multilevel inverters that leads to reduce the inverter costs A conventional 220V 3-ph induction motor has been rewound in order to get the required 48V 3-ph motor. The simulation results are obtained using MATLAB/SIMULINK software.
