Claim 16:
17. The fault handling system of a solid-state transformer according to claim 9, wherein:
the first power unit further comprises a first voltage equalization module, the second power unit further comprises a second voltage equalization module, wherein the first voltage equalization module is connected in series to the second voltage equalization module, the first voltage equalization module is connected in parallel to the two ends of the first busbar capacitor, and wherein the second voltage equalization module is connected in parallel to the two ends of the second busbar capacitor; and
in response to the voltage of the first busbar capacitor being less than or equal to a preset threshold and the first auxiliary supply and the second auxiliary supply both being in a closed state, the first voltage equalization module and the second voltage equalization module equalize the voltages of the first busbar capacitor and the second busbar capacitor.
