Generalized Switch Current Stress Reduction Technique for Coupled-Inductor-Based Single-Switch High Step-Up Boost Converter

Coupled-inductor-based boost converters suffer from high switch current stress in steady state and transient due to less self-inductance value their winding. In this article, a generalized reduction technique is proposed by modifying circuit topology of coupled-inductor-based step-up converter (CIHBC). This achieved half-cycle resonating branch utilizing inductance coupled inductor. Furthermore, applying the concept, inductor for achieving ratio with low voltage stress. The operation using discussed both continuous discontinuous conduction modes. theoretical findings are verified through simulation study PSIM 9.1.1. A prototype 100-W output power designed prove concept performance analysis converter.
