本文提出了两种 DC-DC 转换器，即基于二次升压转换器拓扑的半抽头和全抽头二次升压转换器，用于微型逆变器等高升压应用。所提出的转换器集成了二次升压转换器和基于抽头电感器的转换器的升压能力，因此可以在较低占空比下实现高升压电压增益。此外，所提出的转换器还具有有源开关电压应力低的特点。本文对所提出的转换器进行了详细的稳态分析，其中包括存在寄生组件的情况下的电压增益和效率分析。所提出的转换器的理论分析通过仿真和实验结果得到验证。
This paper proposes two DC–DC converters namely semi-tapped and fully-tapped quadratic boost converter based on the quadratic boost converter topology for high step-up applications such as micro-inverter. The proposed converters integrate the step-up capabilities of the quadratic boost converter and the tapped-inductor based converter due to which high step-up voltage gain can be achieved at lower duty ratio. Further, the proposed converters also have feature of low voltage stress on active switch. This paper presents detailed steady state analysis of proposed converters which include voltage gain and efficiency analysis with the presence of parasitic components. The theoretical analysis of proposed converters is verified by simulation and experimental results.
