A containerization DC ice melting system and control method

A containerization system and a DC control method of melting ice, melting the ice DC loop topology with three-phase system main chain structure, each phase arm and the two upper and lower arm corresponding to the reactor, each arm of N full bridge power module in series, the common connection point of the first end with three-phase bridge arm as a positive DC bus, a common junction point of the trailing end of the three-phase lower arm linked as a negative DC bus; the DC ice melting system attached to the container, is divided into two functionally power box, a coaster brake switch box, clear division structure, easy to transport, simple switching operation required for the operation. The present invention provides a container both DC and ice melting reactive power compensation current ice melting function, attached to the container, easy to transport, the functional configuration of a clear division, less desired Switching switch operation, using common connection point potential bias shift control method of a DC output voltage may be implemented continuously adjustable from zero.
