摘要

针对光伏组件输出电压不稳定的问题,提出一种宽输入电压范围的单电感非隔离型三端口变换器,并通过控制策略可实现3个端口之间的能量流动和功率分配。该文提出的变换器是基于四开关Buck-Boost（FSBB）变换器通过直接构造法和多输入端口构造法结合得到的,光伏组件端口和储能端口串联的结构打破了传统的分时策略的限制,可进一步拓宽变换器的运行范围,同时由于结构特性还可使得三端口变换器的控制器设计得到简化。最后,对提出的拓扑设计实验样机,通过实验验证变换器理论分析的正确性以及在真实的光伏组件中运行的可行性。

Abstract

To address the problem of unstable output voltage of photovoltaic （PV） module, a single inductor non-isolated three-port converter with wide input voltage range is proposed. The energy flow and power distribution among the three ports can be achieved through control strategies.The proposed converter is based on a four-switch Buck-Boost （FSBB） converter obtained by combining the direct construction method and the multi-input port construction method. The structure of the PV module ports and the energy storage ports in series breaks the limitation of the traditional time-sharing strategy, which can further broaden the operating range of the converter, and also simplifies the controller design of the three-port converter due to the structural characteristics. Finally, an experimental prototype is designed for the proposed topology, and the correctness of the theoretical analysis of the converter and the feasibility of its operation in real PV modules are verified through experiments.
