Abstract

See full text

A selective protection circuit includes a current-limiting module and a control module, where the current-limiting module includes a switch unit, and the switch unit includes a first end, a second end, and a control end; the first end is connected to a positive electrode of a bus voltage of an HVDC power supply, and the second end is connected to a positive electrode of a power supply of a voltage pre-regulator circuit in a load branch connected to the current-limiting module; the control end is connected to the control module; and the control module is configured to output a control signal to the control end when a value of a total current flowing through the switch unit is greater than or equal to a preset threshold, so as to switch off the switch unit.
