Embodiment 2

[0029] Embodiment 2: The input port module adopts an AC / DC converter for inputting AC380V power; the bidirectional port module and the output port module are the same as the first embodiment.

Embodiment 3

[0030] Embodiment 3: The input port module adopts two DC / DC transformers for inputting DC1000V power; the bidirectional port module and the output port module are the same as the first embodiment.

[0031] The output of each port module is relatively independent, and the port modules can be configured according to the needs of use, which is compatible with ships of different main grid power systems; and the distributed control method is used to suppress the mutual influence between the port modules, which has the function of "power firewall" Function, avoiding energy impact, effectively isolating power failure, disturbance, harmonic pollution, etc.

[0032] If a DC / DC transformer is selected for the input port module, the energy output terminal of the DC / DC DC transformer is connected to the DC bus bar, and the input port modules other than the DC / DC DC transformer are connected to the energy input terminal of the DC / DC DC transformer , used to isolate the impact of electrical...
