Abstract

A p-type modified quadratic gain buck-boost (PMQBB) converter is proposed in this paper. PMQBB converter topology evolution is based on the integration of a modified quadratic boost configuration with the p-type converter structure. Both of the inductors are in continuous conduction mode (CCM). The proposed PMQBB converters key features include a reduced component count, lower order, high voltage gain, and continuous input current. The proposed PMQBB converter exhibits a buck capability at a duty ratio lower or equal than 0.2929. This paper provides a comprehensive description of the PMQBB converter, including its steady-state analysis, operating modes, and analysis of semiconductor voltage and current stress. To emphasize the PMQBB converter, a detailed comparative study is presented. A 40/400 V, 300 W hardware prototype is tested to authenticate the converter's performance. The experimental outcomes validate the superior performance and efficiency of the PMQBB converter, highlighting its suitability for high-gain applications.

一种用于直流微电网的p型改进二次增益降压变换器

提出了一种p型修正二次增益降压升压（PMQBB）变换器。PMQBB变换器的拓扑进化是基于改进的二次升压结构与p型变换器结构的集成。两个电感都处于连续导通模式（CCM）。所提出的PMQBB转换器的主要特点包括元件数量减少，阶数低，电压增益高，输入电流连续。所提出的PMQBB变换器在占空比低于或等于0.2929时具有降压能力。本文对PMQBB变换器进行了全面的描述，包括其稳态分析、工作模式以及半导体电压和电流应力分析。为了强调PMQBB变换器，本文对其进行了详细的比较研究。对40/ 400v， 300w的硬件样机进行了测试，验证了转换器的性能。实验结果验证了PMQBB变换器优越的性能和效率，突出了其适用于高增益应用。
