Modeling and simulation of closed loop controlled interleaved boost converter system

This paper deals with design calculations and simulation studies of interleaved boost converter cascaded with photovoltaic inverter for residential applications. Interleaved boost converter is mainly used for non conventional energy sources. IBC has two boost converters connected in parallel to reduce the ripple. Low voltage is boosted to higher level using IBC. The open loop and closed loop systems are modeled and simulated. The output waveforms are presented.
