Full Bridge DC-DC Boost Converter with PI Controller for Fuel Cell Applications

Abstract

Fuel cells are considered to be one of the most promising sources of energy because of their high efficiency, low environmental impact and scalability. Unfortunately there are more complications with fuel cell operations. Voltage generated by fuel cell is very low and varies with variation in load. For proper operation of fuel cell based system we need a power conditioner. Power conditioner converts output of fuel cell, 24V DC to 230V AC suitable for residential applications. This paper presents design and analysis of full bridge dc-dc boost converter with PI controller; generate constant output voltage with load variations. Boost converter with PI controller converts output of fuel cell (24V) to constant 400V, which is suitable for inverter.
