An electric vehicle power train with regenerative braking technology and sensorless control of PMBLDC motor which is powered by solar-PV and battery system is described in this paper. Third harmonic stator flux-based rotor position estimation technique is used, which has the benefits of wider speed range. Phase current sensors are eliminated in this proposed system, and the speed is controlled online in accordance with the peak power available from solar-PV panel and the load demand. The battery is being charged from the vehicle’s kinetic energy during braking and making it possible to achieve regeneration. In this process intermediate DC-DC converter stage is eliminated. Noninverted zeta converter with continuous output current ensures efficient MPPT control of solar-PV array. Switches of the VSI are gated at fundamental frequency thus reducing losses associated with high frequency switching. The designed system is expected to be robust in terms of stability and controllability.
