This paper describes a new interactive inverter between a photovoltaic(PV) array and single-utility that avoid the bulky input (60Hz) transformer on the AC side The interface employs a pwm boost converter on the DC slde followed by a pwm current-forced single-phase rectifier for injecting the power from the PV array into the mains. The current waveform at the AC side remains sinusoidal and exactly in phase at all time. The circuit also has the advantage of requiring fewer switching device than high-frequency link system. This paper describes modeling of PV array and new system topology Simulation results on the performance of the connection are also presented
