This paper presents a grid connected photovoltaic system (PV) with a proposed\nhigh voltage conversion ratio DC-DC converter which steps up the variable\nlow input voltages of photovoltaic module to the required DC link voltage.\nThis voltage is applied to an H-bridge inverter which converts DC voltage\ninto AC voltage and a low pass filter is used to filter the output. By adjusting\nthe duty ratio of switches in DC-DC converter, the magnitude of inverter�s\noutput voltage is controlled. The frequency and phase synchronization\nare ensured by a feedback signal taken from the grid. In this way, inverter\nis synchronized and connected with the grid to meet the energy demand. The\nPV system has been designed and simulated.
