L-Impedance Network based DC-DC Converter with CLD Cell Integration

Abstract

In this paper a novel L-impedance network based DC-DC converter integrated with capacitor-inductor-diode (CLD) cell is proposed. The L-impedance network based DC-DC converter is also named as switched inductor boost converter (SIBC) due to its high boosting nature of voltage. The inductors present in the SIBC are responsible for boosting nature and hence high voltage gain. The CLD cell consisting of two diodes, two capacitors and one inductor integrated with SIBC simultaneously increases the voltage gain as well as reduces the voltage stress across the active switch of DC-DC converter. So, the proposed SIBC-CLD has high voltage gain with reduced voltage stress in the active switch. The analysis is carried out through Matlab/Simulink in order to validate the theoretical aspects. Along with this a detail comparison has been made between the proposed SIBC–CLD with classical boost converter (CBC), classical boost converter with CLD (CBC-CLD) and classical switched inductor boost converter (SIBC).
