High Gain Converter with Switched Coupled Inductors for Renewable Energy Systems

Switched coupled inductor boost converter (SCIBC) for renewable energy systems is outlined in this paper. The proposed converter will be obtained from a combination of traditional step-up converter and coupling inductor stacks. The proposed converter’s gain is determined by the number of couple inductors within the stack and duty cycle. The proposed converter refers to a single regulated power electronics switch. The frequency of 10 MHz is applied to lower the L, C values and to eliminate the ripples of the output signal (Vout and Iout). Proposed converter design and function are explored in depth. The proposed converter for single couple inductor stack is simulated in MATLAB (version 2015b), and the outcomes are checked using theoretical values and reliability of the BLDC motor drive at constant speed with closed-loop flyback converter.
