The invention provides a multi-port energy storage converter which comprises a first converter module, a second converter module and a switch module, the first converter module comprises a first converter unit and a first switch unit, and the second converter module comprises a second converter unit and a second switch unit. One end of the first converter module is used for connecting an AC power supply system, the other end of the first converter module is connected with the switch module and the second converter module, the switch module is also used for connecting DC equipment, and the second converter module is also used for connecting DC equipment. According to the application, the first converter module and the second converter module are combined, so that the voltage range of the direct current side is wide, and the battery adaptability is good; the first converter unit, the first switch unit, the second converter unit and the second switch unit are connected with the switch module; mutual switching between alternating-current energy storage and power supply and direct-current energy storage and power supply is achieved through on-off of the switch units and the switch modules, and therefore the use cost can be remarkably reduced.
本申请提供了一种多端口储能变流器,包括第一变流模块、第二变流模块及开关模块,第一变流模块包括:第一变流器单元以及第一开关单元,第二变流模块包括:第二变流器单元以及第二开关单元,第一变流模块的一端用于连接交流供电系统,第一变流模块另一端与开关模块以及第二变流模块连接,开关模块还用于连接直流设备,第二变流模块还用于连接直流设备。本申请结合第一变流模块和第二变流模块,使直流侧电压范围宽,且电池适应性好,由于第一变流器单元、第一开关单元、第二变流器单元和第二开关单元和开关模块的连接,通过各开关单元和开关模块的开断实现交流储能及供电和直流储能及供电间的相互切换,进而能够显著降低使用成本。
