A New Multilevel Member of Modified CUK Converter Family for Renewable Energy Applications

Abstract

A new multilevel family member of Modified CUK Converter (MCC) by topping up with Voltage Multiplier (VM) to term as MCCVM is developed in this article. Suitable goal to generate high-voltage output and fits the renewable energy applications. By integrating the specific arrangement of diodes and capacitors in MCC, the voltage gain is boosted in the proposed MCCVM converter. An effective solution for renewable energy applications such as PV, fuel cell, etc. Features of the proposed converter are (a) single switch topology which required simple digital control scheme, (b) low-voltage stress on switch as compare to the output voltage, (c) continuous input current, (d) inverted output with respective to the input voltage. The operating principle, the mathematical derivation of proposed MCCVM converter are discussed in the paper. The functionality and performance of the proposed high-voltage converter are verified by means of MatLab (R2016a) numerical simulation. Followed by the experimental verifications through hardware prototype model and which always show a good agreement with the numerical simulation and theoretical analysis.
