Abstract

This article introduces a quadratic high stepup DC–DC converter that incorporates a switched inductor–capacitor network. The proposed converter is intended to align the voltage at the output terminals of the converter with the DC link voltage suitable for renewable energy sources such as solar photovoltaic systems and fuel cells. The converter provides a superior voltage conversion ratio over an extensive range of duty cycles. To validate its functionality, the converter is assessed under both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). The influence of parasitic components is taken into account to precisely evaluate the DC voltage gain. The circuit’s performance is evaluated against existing topologies concerning the voltage conversion ratio, voltage stresses encountered by the switches, and maximum voltage gain. A 300 W hardware prototype was constructed and evaluated. The proposed converter, operating with a 24 V input source, delivers an output voltage of 380 V as confirmed by experimental results.
