High-performance analysis of interleaved high-gain converter with active switched inductor using intelligent controller

Performance analysis of the interleaved high-gain converter with active switched inductor using an intelligent controller is presented in this article. In this proposed work, an intelligent controller is designed for an interleaved high-gain converter to enhance the performance in terms of high voltage gain, less input current ripple, output voltage ripple and high efficiency. A large amount of input ripple current is generated due to parallel charging of the inductor (ON and OFF time interval). This high ripple current will cause heating in circuit elements and also reduce the efficiency of the system. Furthermore, it also reduces the current carrying capacity of the inductor by 50%. The continuous power to the load is delivered, by turn on of a pair of semiconductor switches alternatively, i.e. 180⁰ phase shift between the converters. The dynamic performance of the converter is evaluated in terms of line and load disturbances with the help of an intelligent controller and the performance comparison of the converter is also carried out with respect to the duty cycle. This intelligent controller-based converter is simulated using MATLAB/Simulink software, and results are verified through field programmable gate array (FPGA)-based experimental setup.
