Abstract
Integrating the power from the photovoltaic (PV) module into the existing power distribution infrastructure is achieved using power conditioning systems (PCS). The DC–DC conversion stage of the PCS requires a high efficient and high boost ratio DC–DC converter to increase the low DC input voltage from the PV panel to a higher DC voltage. In this article proposes, the backstage power circuit consists of a high boost ratio hybrid transformer DC to DC converter and a full-bridge inverter to convert DC-AC, as the grid voltage is AC in nature. Total Harmonic Distortion is generated by inverter which is minimized by using a low pass filter so that the system is within its acceptable limits. A feedback loop is used in the boost converter to control the converter output voltage. Phase control circuit is required to maintain a constant output voltage at the load side since the PV system output voltage varies continuously in nature.

Key-Words / Index Term
