摘　　要：研究了一种用于微电网分布式发电的新型Buck-Boost逆变器。分别从新型逆变器拓扑结构、工作模态和控制策略进行了分析。以光伏发电为应用场景,探讨了新型逆变器的剩余电流特性。经仿真和试验验证,理论分析是正确、有效的;同时表明新型Buck-Boost逆变器具有结构简单、输入电压范围宽、效率高、可靠性高等特点。The derivation of the novel inverter topology was implemented, and the operation modes and control strategy were analyzed. With the application case of solar generation, the residual current performance of the novel inverter was specifically investigated. Finally, the simulation and experiments were conducted to verify the correctness and effectiveness of the theoretical analysis. It is demonstrated that the proposed novel Buck-Boost inverter features are simple stIucture, wide input voltage range, high efficiency and high reliability.
