摘要

提出了一种基于两个基本开关单元非级联连接的二次型降压-升压变换器。将所提出的变换器分析为串联的光伏结构。推导了电压转换比、稳态工作条件、变换器工作模式以及半导体电压和电流应力。仿真结果验证了该变流器的特性，其中光伏系统的布局采用两个二次型变流器，每个变流器都采用MPPT P&O策略。

Quadratic Buck/Boost Converter in Series Connection for Photovoltaic Applications

This paper proposes a quadratic buck-boost converter, which is based on a non-cascade connection of two basic switching cells. The proposed converter is analyzed into a photovoltaic architecture in series connection. The voltage conversion ratio, steady state operating condition, converter operating modes, and semiconductor voltage and current stress are derived. The characteristics of the proposed converter are verified through simulation results, where the layout of the photovoltaic system uses two quadratic converters, each with an MPPT P&O strategy.
