Abstract

This paper proposes a novel non-isolated high gain DC-DC multi-input single-output (MISO) boost converter for sustainable energy applications. The proposed converter is ideal for translating the voltage from two separate sources with different voltage levels to a higher voltage. The two-stage MISO boost circuit is derived by incorporating the enhanced circuit from its elementary boost converter. Six power semiconductor devices are used to maintain the power transfer. Since the voltage stress of the switches is low, the conduction loss is limited. Thus, the converter obtains a high conversion ratio and high performance at the same time. The operation, steady-state analysis and control system of the converter are explained. The selection of the components and a performance analysis are presented and tested by comparable findings. MATLAB/Simulink is used to perform simulations of the suggested converter topology. With the MATLAB auto code generation tool for Texas Instrument C2000-based microcontrollers, the power flow regulation of the converter is designed and evaluated. A prototype of the proposed converter with a two-input voltage source is fabricated and tested.
