Multi-stage switched-inductor switched-capacitor high gain DC-DC converter.

This paper presents a Multi-stage Switch Inductor Switch Capacitor High Gain DC-DC Converter for microgrid application designed with integrated Active Switch Capacitor (ASC) and Active Passive Inductor Cell (APIC). The closed loop control of a proposed voltage lift DC-DC converter is performed to ensure the constant output voltage disregarding the change in input voltage. The new high gain extendable DC-DC boost converter topology is capable of providing high-gain voltage with low duty cycle and it is extendable by increasing the number of APIC network. Analytical modelling of the proposed converter is carried out to obtain the technical specifications. The open loop and closed loop simulation model of the proposed converter is developed in the MATLAB/Simulink environment to analyse the performance of the converter. The microcontroller-based hardware model of the proposed converter of power rated 200 W (18/200 V at 50% duty ratio) is developed and tested in open loop to validate the simulation results and experimental set-up results are reported.
