Zusammenfassung: | The invention provides a direct-current solid-state short-circuit current limiter, a control method thereof and a flexible direct-current power supply system. The direct-current solid-state short-circuit current limiter comprises an auxiliary turn-off module, a main through-flow module and a current limiting module, the first end of the auxiliary turn-off module is the input end of the direct-current solid-state short-circuit current limiter, and the second end of the auxiliary turn-off module is electrically connected with the first end of the main through-flow module and the first end of the current limiting module. The second end of the main through-flow module is electrically connected with the second end of the current limiting module and serves as the output end of the direct-current solid-state short-circuit current limiter, the main through-flow module at least comprises a plurality of power electronic devices, and the auxiliary turn-off module is used for reducing turn-off current when the power elec |
