- 3. Abstract Hybrid Electric vehicle (HEV) technology provides an effective solution for achieving higher fuel economy and better performances with reduced greenhouse gas emissions. For Electric vehicle applications, Switched reluctance motor (SRM) is the best suitable one of all the available motors. To increase the driving miles of the electric vehicles, a photovoltaic (PV) panel is mounted along with on-board battery bank. A tri-port converter with fuzzy logic controller is proposed in this paper to control the energy flow between the PV panel, battery and SRM drive. Six operational modes are presented, four of which are developed for driving modes and rest two for stand still on-board charging.
- 4. Introduction Electric vehicles have taken a significant leap forward, by advances in motor drives, power converters, batteries and energy management systems be that as it may, due to the limitation of current battery technologies,the driving miles is moderately short that limits the wide utilization of Evs. SRM needs no rare-earth PMs and is additionally robust so it gets increasing attention in EV applications. While PV panels have low power density for traction drives, they can be used to charge batteries the greater part of time. For the most part, the PV-fed EV has a comparable structure to the hybrid electrical vehicle, whose internal combustion engine(ICE) is supplanted by the PV panel.

- 12. Advantages PV-fed EVs are a greener and more economical innovation than conventional ICE vehicles. This will give feasible solution to reducing the total costs and CO2emissions of electrified vehicles. By using different control strategies in each mode we can reduce the Total Harmonic Distortion to some extent . Fuel cells have a considerably higher power density and are hence more qualified for EV applications.
- 13. conclusion A tri-port converter is utilized to coordinate the PV panel, SRM and battery. Six working modes are developed to achieve flexible energy flow for driving control, driving/charging hybrid control and charging control. A novel grid-charging topology is formed without a need for external power electronics devices. A PV-fed battery charging control scheme is developed to utilization of solar energy.
