Abstract:
1. A power switch series circuit, comprising: a first series module comprising a first power switch; a second series module adjacent to the first series module, comprising: a control module electrically connected to the isolation unit for receiving the voltage detection signal and outputting a control signal corresponding to the voltage detection signal; and a drive module electrically connected to the control module, the first terminal of the second power switch, the first power switch and the third power switch, the drive module amplifying the control signal to drive the first power switch, the second power switch and the third power switch to turn ON or turn OFF; wherein when the detected voltage is higher than a first threshold voltage, the voltage detection signal is the overvoltage signal, and the control module outputs the control signal corresponding to the overvoltage signal, so as to turn OFF the first power switch, the second power switch and the third power switch.
