Fuel Cell Based Single Phase Pure Sine Wave Inverter with PI controller

Abstract

Renewable energy plays an important role in our life over last few years. As we seen that cost of electricity and their resources day by day increasing. Fuel cell is the best way to fulfill the requirement of energy. It is a clean, efficient and pollution free source of energy. In this paper modeling and simulation of fuel cell based single phase inverter with PI controller is presented. Fuel cell based power supply needs a power conditioner which convert dc output voltage of the fuel cell  which is very low into usable ac voltage, sufficient for residential applications. Power conditioner is a combination of DC-DC full bridge boost converter and inverter. Full bridge boost converter step up the output of fuel cell (24V) to regulated high voltage(400V) and inverter converts this voltage to pure sinusoidal 220V,50Hz AC voltage. Sine Pulse width Modulation(SPWM) technique for controlling of boost converter and PI controller used for controlling of inverter.
