[0031] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.
[0032] Such as figure 1 As shown, the present invention is described for a new type of electrical isolation DC transformer.
[0033] The commonly used control methods for each port of the electrical isolation DC transformer mainly include constant DC voltage control, constant AC voltage control and constant power control. The transformer can adapt to the matching of voltage level and power through the series and parallel connection of power modules, so as to be suitable for Different applications. In addition, the transformer has a positive and negative topological structure, which can operate independently.
[0034] Such as figure 2 As shown in the typical network topology of the DC grid, in normal operation, the converter T1 (positive and negative poles are T11 and T12 respectively) is in constant DC voltage control...
