Abstract
The present disclosure provides a power semiconductor switch series circuit. The power semiconductor switch series circuit includes a plurality of series modules and a system control module. Each series module has a power semiconductor switch; a drive module for driving each power semiconductor switch to be turned on or turned off; a short-circuit detection unit for outputting at least one detection signal; an equalizer circuit; a comparison module for comparing the detection signal with a predetermined threshold, and outputting a short-circuit signal when the detection signal exceeds the predetermined threshold; and a soft turn-off module for receiving the short-circuit signal and outputting a second control signal. The system control module receives the short-circuit signal and outputs a first control signal.
