Multiport energy router and its control system and control method

摘要

The present invention discloses a multiport energy router comprising at least two multiport modules. Each multiport module includes a first common port and a second common port, and at least one remaining port, the first common port being a DC port connected to or not connected to the DC bus. The second common port is connected to an AC bus or a DC bus, and all other ports can be designed according to actual usage requirements. According to this structure, it is possible to provide a method for supplying electricity according to a multi-port having a distributed characteristic, which can be applied to various types of voltage levels of electric energy, and can preferably solve the voltage balance problem existing in the prior art. The present invention also discloses a control system and control method of a multi-port energy router.
