摘要： 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.

摘要： The present invention provides a power switch series circuit and its control method. The power switch series circuit includes a plurality of series modules, a control module and a drive module. At least one series module has a power switch and a detection module, and the detection module includes a detection unit and an isolation unit, so as to detect the overvoltage and output a voltage detection signal based on the detected voltage. The control module receives the voltage detection signal and outputs the corresponding control signal. The drive module amplifies the control signal to drive each power switch to turn ON or turn OFF. The control module outputs the corresponding control signal to turn off each power switch when the overvoltage happens.
