The invention relates to a converter with an AC/DC charging and discharging function, and the converter comprises a buck-boost module which is connected to a four-leg module and comprises a battery interface for connecting to a battery; the four-bridge-arm module is also connected to the power distribution module; and the power distribution module is configured to enable the four-leg module to be in a first electric topological structure so as to receive or output alternating current through the alternating current input/output port when the power distribution module is in a first state, and to enable the four-leg module to be in a second electric topological structure so as to receive or output alternating current through the alternating current input/output port when the power distribution module is in a second state. And the four-leg module is in a second electric topological structure so as to output direct current through the direct current output port.

    本公开涉及一种具有交直流充放电功能的变换器,包括:升降压模块,所述升降压模块连接到四桥臂模块并且包括用于连接到电池的电池接口;所述四桥臂模块,所述四桥臂模块还连接到配电模块;以及所述配电模块,所述配电模块被配置成在处于第一状态时,使得所述四桥臂模块处于第一电拓扑结构以通过交流输入/输出端口来接收或输出交流,而在处于第二状态时,使得所述四桥臂模块处于第二电拓扑结构以通过直流输出端口来输出直流。
