Analysis of a Modified Interleaved Non-Isolated Cuk Converter with wide range of load Variation and reduced Ripple content

Abstract

This Paper Present here with an aim to analyze, simulate and examine the Operation of non-isolated interleaved Cuk/Chook (step up mode) Converter. Here, Input Voltage of proposed Converter was maintaining below the 50 V to keep the cost of our operation low and moderate. Existing Traditional Cuk converter (TCC) has the Continuous Current at input as well as output side. This proclivity of Converter is taken for our performance Observation to analyse the behaviour of proposed Structure. In Accordance with that, non-isolated interleaved Cuk/Chook Converter(ICC) is to be schemed/overtures and simulated here, to inspect the reduction in the ripple content on input and output waveform and it also enhances the Settling time of system. These unwanted ripple content is diminished or almost eliminated by implementing the Interleaved structure to existing converter topology with the current and voltage feedback control loop. Cuk Converter topology (TCC and ICC) gives output voltage with negative Polarity as compared to input voltage polarity. This interleaved configuration of converter is useful to achieve high gain and efficiency with limited duty cycle and wide load variation range.
