Pv-Fc systems fed multilevel inverter by employing Pi controller

Abstract

This paper presented a seven level Photovoltaic (PV) solar cell system & Fuel cell designed in support of grid connected network by employing Pulse Width Modulation control scheme. The input power source comprises of PV source & Fuel cell. Modified MPPT algorithm (P&O) is use just before take out the maximum control from Photo voltaic system. The structure of the circuit is multi modular towards convert dc input voltages to dc output voltages among low rate devices at low duty cycle. A Proportional Integrate controller is to be implementing for multilevel inverter operating & closed loop analysis is done. One reference signal is to be impossible to tell apart to each other by means of an balance equivalent towards the triangular signal are used to make PWM signals intended for the switch. In the Proposed system will be verified during MATLAB/Simulink. The tentative result is compared among the predictable distinct phase seven level grids connected with Pulse Width Modulation generator.
