DESIGN AND SIMULATION OF PWM FED TWO-PHASE INTERLEAVED BOOST CONVERTER FOR RENEWABLE ENERGY SOURCE

Recently dc-dc converters is serving many purposes and is usually required in any applications which has low output voltage such as Fuel cells, Batteries, photo voltaic cells. For designing high efficiency fuel cells which is a clean energy source and has a high energy storage capability, a suitable dc-dc converter is required. One of the challenges in designing the boost converter for high power application is to how to handle the high current at the input side. Among the various topologies IBC is a better solution for fuel cell systems due to its increased efficiency, reduced size, current sharing on high power applications, low input current ripple and improved reliability. The various parameters of the PWM based IBC are compared to a conventional boost converter. Simulation studies has been carried out using MATLAB/SIMULINK.
