This paper introduces a single-switch high-gain voltage-multiplier coupled quadratic boost converter (HGVM-QBC), developed from the conventional quadratic boost converter (QBC). The proposed topology is designed to achieve higher voltage gain, lower semiconductor voltage stress, and continuous current operation, making it particularly suitable for small-scale photovoltaic (PV) systems. By incorporating a voltage multiplier cell into the QBC, the converter significantly improves voltage boosting capability while mitigating stress on switching devices. In this configuration, the output voltage is obtained by combining the voltages across multiple output capacitors, thereby enhancing the overall voltage level. A detailed comparative study with recently reported converter topologies demonstrates the superior gain and reduced device stress offered by the HGVM-QBC. The design is validated through MATLAB/Simulink simulations, which confirm improved performance in terms of gain and voltage stress. Furthermore, an experimental prototype achieves an output of 151 Vdc from a 12 Vdc input at a 55% duty cycle, corresponding to a gain of 12.59. These results establish the HGVM-QBC as an efficient and reliable solution for PV applications that demand high voltage output from low input sources.
