The Plug-in hybrid electric vehicles (PHEVs) are an evolution from the hybrid electric vehicles(HEV) which has both IC engines and electric motors along with the battery. The benefit of PHEV is that we can charge the battery from the power grid even at home or that work utilizing the charging ports and accordingly diminishes the general fuel utilization. This paper proposes an integrated power electronics module for PHEV. It consists of a Z source sparse matrix inverter and an isolated DC/DC converter. In the proposed configuration, the z source sparse matrix inverter is developed in such a way that it works in both the directions. When the battery is getting charged from the power grid (G2V mode), it acts as AC/DC converter and when the converter is operated in the other mode (V2G mode) i.e. when power is transferred from the battery to the power grid it operates as a DC/AC inverter. During this operation the voltage transferred by the battery to the power grid may be less. So in order to increase or boost the voltage from the battery to the power grid, a DC/DC converter is used. In order to validate the functioning of the proposed module, the indirect space vector pulse width modulation technique is used. This technique will increase the efficiency of the converter and also reduces the total harmonic distortion (THD) of the input current in the V2G mode. The proposed module is examined and the performance is proved using the simulation results obtained in MATLAB SIMULINK. Further, the experimental setup of the integrated system is under progress.
