Hybrid electric vehicles (HEV) have attained a remarkable significance in automotive industry and continuous research is carried on optimisation of HEV. This paper attempts to enhance the performance of HEV by employing new stepped DC link coupled Quasi Z inverter. The proposed inverter aids efficient source management and offers simplified power conditioning circuitry for HEV. The hybrid topology ensures continuous operation of the drive for varied asymmetrical inputs and the self-boost nature lessens the source requirements. The mitigated harmonics with reduced stress on components, poses improved efficiency of 4.87% and reduction in torque ripple by 1% as compared to its predecessor fed to HEV. Simulated and experimental results using the designed prototype validate the proposed theoretical model. Furthermore, this paper analyses all the operating states of the proposed module and the performance of the integrated system is evaluated for various input conditions. Loss calculation and efficiency Assessment is performed to ascertain the advantages of the proposed inverter with HEVs.
