Abstract: This paper presents a complete design and control of solar assisted passenger car electric engine which aims to overcome the disadvantages associated with present E-Rickshaw. Here a permanent magnet synchronous motor (PMSM) drive is considered as main electric engine fed from Battery and Solar PV cell. Generally in VSI fed PMSM drive the dc input voltage to the inverter is kept constant irrespective of the load demand. This leads to more losses in the dc bus and overall efficiency of the system decreases. This paper presents a noble control technique with variable dc link voltage to improve the efficiency of the PMSM drive by minimizing the dc link power losses. An additional separate PI controller is used to control the dc link voltage which adjusts dc- link voltage indirectly. The design of PI controller with basic principles is illustrated and the necessary conditions are analyzed. This control scheme is tested with a 25kW Permanent magnet synchronous motor (PMSM) drive suitable for application in electric vehicle. The effectiveness of the system is verified through simulation using Simulink/ MATLAB.
