A Double-Switch High Gain DC-DC Converter Based on Coupled-Inductors

Abstract

<p>An innovative high voltage gain dc to dc boost converter using extendable diode-capacitor voltage multiplier cells (VMC) is discussed and recommendations. Furthermore, the primary and supplemental power MOSFETs of the given converter use zero voltage switching (ZVS). In the described design, diode-capacitor VMC and Coupled inductors (CI) are used to obtain a greater voltage gain. The leakage inductances of the CIs limit the levels of current drop in the diodes of voltage multiplier, significantly lowering its reverse recovery loss. Furthermore, the voltage stress across all capacitors and components are greatly decreased. The offered converter's structure and theoretical analysis are described. Furthermore, the experimental results will validate the theoretical analysis.</p>
