一种具有有源功率解耦功能的新型单相非隔离双输入微型逆变器

Aiming at the challenges faced by single-phase nonisolated microinverters (MIs) such as leakage current and power fluctuation, a nonisolated common-ground MI with active power decoupling capability is proposed in this article. In this topology, the photovoltaic (PV) module and the grid have a common terminal, thereby eliminating the common-mode leakage current. Power decoupling between dual-input ...
