The Increasing Number of renewable energy sources and distributed generators requires new strategies for the operation and management of the electricity grid in order to maintain or even to improve the power-supply reliability and quality. We present power-conditioning systems used in grid-connected photovoltaic (PV) generation plants. The continuously decreasing prices for the PV modules lead to the increasing importance of cost reduction of the specific PV converters. This paper presents Integrated Electric Motor Drive and Power Electronics for Bidirectional Power Flow between the Electric Vehicle and DC or AC Grid. The three phase machine windings and the three inverter phase legs can be utilized with an interleaved configuration to distribute the current and reduce the converter switching stresses. The battery voltage is increased in the boost mode to an output reference voltage level within the limits of the machine ratings. A soft starter method using PWM control has been used to reduce the starting current overshot when connecting to a dc grid. In a dc grid connected mode, the voltage drop across the inductor will be the difference between the inverter output voltage and the dc grid voltage. The dc grid voltage provides more stable voltage to counteract the rate of change of inductor current and the current ripple is controlled in a better fashion in a dc grid connected mode. The Proposed method will have simple converter systems which used for different modes of operation there by size can be reduced. Finally the proposed method developed by using Matlab/Simulink software.
