PV Fed Interleaved Superboost Converter with MPPT Controller for Renewable Energy Applications
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 0
Abstract
Generally high voltage boost gain cannot be achieved in conventional step-up converters since the parasitic parameters will set an upper limit on the duty ratio at which the converter can efficiently operate. In recent years many high step-up DC-DC converters have been proposed. Among the developed converters, the high step-up single switch converters exhibit large input current ripple which make them unsuitable to operate at heavy load due to high conduction losses. So a new super boost converter is designed. This converter consists of switched capacitors and two coupled inductors. This combination of coupled inductors and switched capacitors can provide high voltage boost gain while operating with small duty cycle. By using one individual DC voltage source in an interleaved manner the converter can be powered. The configuration of the proposed converter advantages such as low power losses, longer lifetime of input sources due to non-pulsating input current, low voltage stress across the main switches and slow output fluctuation. The concept is to constant voltage By implementing this converter a 22.5 times gain can be reached 0.5 duty ratio and turns ratio equal to 2.Simulation results will be presented to demonstrate the authenticity of the proposed converter.
