Abstract
This paper proposed modified version of Switched Inductor Boost Converter (SIBC), which has the following key features: high voltage conversion along with voltage-stress reduction across power electronic switch. The suggested boost converter is derived by substituting power electronic switch and capacitor in place of two diodes present in SIBC. With the offered modification, the output voltage is equally divided between two switches. Hence, the suggested boost converter operation ensures reduction in switch voltage stress. In addition, the proposed boost converter attains improved voltage gain without any further extension of component count and exhibits a common ground between input and output terminals. Using closed loop control, the proposed boost converter is tested in MATLAB Simulink for 500 W load, output 400 V and input 48 V. The simulation analysis is presented for steady state and dynamic conditions of the proposed boost converter operation. Thus, theoretical analysis and proficiency of the proposed boost converter with the closed-loop control is validated.
