Abstract

With the development of renewable energy, the demand for related power equipment is growing. This study addresses the issues of high voltage and current stresses on switching devices in conventional quadratic Boost converters under high-voltage-gain applications, and proposes a novel quadratic switched-capacitor Boost converter topology. The proposed topology incorporates a series charge–discharge switched-capacitor structure and optimizes the energy storage stage. By analyzing the converter’s operating principles during the switch-on and switch-off states, the mechanism for voltage gain enhancement is elucidated. Under a typical operating condition with a 45% duty cycle, simulation results verify that when the input voltage is 20 V, the output voltage reaches 117.2 V, yielding a gain of 5.85, while maintaining low average inductor currents, with 1.57 A for L1 and 1.79 A for L2. Moreover, the voltage stress on switch S1 is reduced to 0.25 u0. This topology offers a high-efficiency, low-stress DC–DC conversion solution for renewable energy applications such as photovoltaic generation and fuel cell systems.
