Abstract
A solid state transformer (SST) is provided, and is concerned with improving the fault tolerance of the SST. A method of operating the SST and an SST device including the SST are also provided. The SST has three parallel phase branches each having multiple cells, and each phase branch is connectable via a switch to a power grid. The method comprises operating the SST in a first control mode, in which each of the three phase branches is individually controlled. Further, when an open-circuit or short-circuit fault occurs in a cell of a particular phase branch, the method further comprises opening the switch connecting the particular phase branch to the power grid, and operating the SST in a second control mode, in which the two phase branches other than the particular phase branch are jointly controlled as a single phase branch.
