Overview

Experimental evaluation demonstrates high voltage gain and reduced semiconductor stress using a cascaded quadratic converter, highlighting improved power density for automotive photovoltaics.

Key Points

To develop and evaluate a non-isolated, high-gain quadratic boost DC–DC converter with zero-current clamping diodes and buffer capacitors for low-power photovoltaic applications.
Engineered a quadratic topology integrating two coupled inductors, switched capacitors, a voltage-multiplying cell, two power switches, and zero-current clamping diodes.
Derived steady-state operating equations, generalized voltage gain formulations, and theoretical efficiency models using a common-ground configuration.
Constructed and tested an experimental hardware prototype specified for a 400 V output to validate performance.
Delivered high voltage gain using lower turns ratios and duty cycles compared to conventional square-law converters.
Lowered electrical voltage stress across semiconductor switches and diodes while supporting closed-loop control via a common ground.
Demonstrated higher power density, a smaller footprint, and high operational efficiency confirmed by the 400 V laboratory prototype.
