Research of bidirectional DC-DC converter in distributed wind-photovoltaic-storage system
摘要
Abstract
This paper proposes a system topology structure of the distributed wind-photovoltaic-storage system and mainly researches on a bidirectional DC-DC converter which connects the battery and DC bus.The bidirectional DC-DC converter can implement the power exchange among solar panels,wind turbine,grid and the battery,and adjusts the busbar voltage,which is the key part of the whole system.We use high step up double active full bridge DC-DC converter as the bidirectional DC-DC converter.It can connect the low voltage battery and the high voltage DC bus,and furthermore,it can implement the bidirectional power flow and soft switching by phase shifted control.A 3kW prototype is built up to test the bidirectional DC-DC converter under different working conditions.关键词
