中点钳位非隔离全桥光伏并网逆变器
Neutral Point Clamped Non-isolated Full Bridge PV Grid-connected Inverters
摘要
Abstract
Two types of basic switching cells,positive-neutral point clamped cell and negative-neutral point clamped cell,and a method to build neutral point clamped（NPC） full bridge photovoltaic（PV） grid-connected inverters with these two basic cells are proposed to meet the demand for non-isolated inverter topology applied in PV generation system.A family of novel NPC non-isolated full bridge PV grid-connected inverters,besides existing topologies such as oH5 and FB-DCBP,is derived.Operation modes of the PN-NPC topology are analyzed as an example in detail.Finally,both of the efficiency and common-mode performance of the proposed PN-NPC and Heric topologies were compared with experimental results.And the comparison results show that the proposed PN-NPC topology features better efficiency and common-mode performance than that of the Heric topology.关键词
