Hardware Implementation of a High Step up DC-DC Converter Using Photovoltiac System

Abstract

A high step up DC input voltage is a most critical requirement of various electrical applications. A high step up DC DC converter using photovoltaic system is a worthy solution of this need. Due to coupled inductor with a capacitor charge in parallel and discharge in series which increase the voltage transfer gain. this converter can accomplish high duty ratio with high step up voltage gain. Also voltage stress on main power switch can be reduced by minimizing the conduction losses and improving efficiency. This paper has incorporated technique for hardware implementation of a high step up DC DC converter using photovoltaic system. In this project coupled inductor with switching capacitor technique are developed to make hardware circuit for input of 12v from the PV panel, output voltage of 100v across the load and power of 354W. Finally, to check its performance the prototype circuit also developed.
