DESIGN HIGH GAIN DC-DC BOOST CONVERTER WITH COUPLING INDUCTOR AND SIMULATION IN PSIM

Abstract

The high gain DC-DC converter with coupling inductor is design to boost low voltages to voltages into high range of 30 to 50 times input voltage. It is especially useful in boosting low solar panel voltage (12V) to high voltage, so that 230V ac can be generated. At the time the efficiency is also high and it is cost effective. It is a transformer less topology. This converter will work with input voltage of 12Vdc, and generate constant output voltage of 360Vdc with the help of PI controller. To achieve high voltage output gain the converter output terminal and boost output terminal are connected in serially with the isolated inductor with less voltage stress on controlled power switch and power diodes. PSIM software has been used for simulation.
