Abstract: The pollution of environment is increasing due a very large numbers of conventional cars present today. To reduce pollution the electric hybrid electric vehicle are very beneficial. As the era of cheap fuel is also coming to an end the hybrid electric or electric vehicle is a good alternative to the conventional cars. In the paper, the optimization design and analysis of a 30kW interior permanent magnet synchronous motor (IPMSM) used in electric vehicles are fulfilled by finite element analysis (FEA). In order to satisfy good control performances, low cost and high reliability ,Simulation and experimental verification of the prototype are compared deeply, and the final comparison results indicate the prototype essentially satisfies the design In this project the survey of Electric car is done, also a new design of integrated circuit of inverter/converter is introduced to increase the efficiency of the hybrid electric cars & comparison of this technique with other control methods for HEV/EVs is being done. In this system it is given that at starting we need high starting torque for HEVs so we will use two PMSM (permanent magnet synchronous motor) motor feeding by two distinct Inverters sources. After staring we need high acceleration so we will use one of the Inverter & PMSM motor set as a DC-DC boost converter to assist other Inverter to increase the DC link voltage of that inverter to increase the output voltage & power. This integrated circuit allows the Permanent magnet synchronous motor (PMSM) to operate in motor mode or acts as a boost inductor of a boost converter, thereby boosting the output torque coupled to the same transmission system. In motor mode, the proposed integrated circuit acts as an inverter and it becomes a boost-type converter, while using the motor windings as the boost inductors to boost the converter output voltage. Therefore, the proposed integrated circuit can significantly reduce the volume and weight of the system.
