Claim 5:
6. The fault handling system of a solid-state transformer according to claim 4, wherein:
the first control module further comprises a first control circuit, the second control module further comprises a second control circuit, wherein the first control circuit is electrically connected to the first communication module, and wherein the second control circuit is electrically connected to the first communication module;
the first control circuit is further configured to transmit the fault information to the second control circuit by using the first communication module in response to the voltage of the first busbar capacitor and detected by the first detection circuit being greater than or equal to the first threshold and the first control circuit controls a status of the first auxiliary supply based on the voltage of the first busbar capacitor; and
the second detection circuit transmits the detected voltage of the second busbar capacitor to the second control circuit and the second control circuit is further configured to close the second auxiliary supply in response to receiving the fault information.
