  • POWER SUPPLY FOR CONTROLLING A POWER SWITCH
    Publication number: 20140191793
    Abstract: It is presented a power supply for providing power to control a power switch for a high voltage application. The power supply comprises: a high voltage divider arranged to be connected to a first current terminal of the power switch; a step down DC/DC converter connected to an output of the high voltage divider, wherein the step down DC/DC converter is arrange to provide an output voltage for control of the at least one power switch to an output of the power supply; and a bypass control unit arranged to control the high voltage divider to short circuit an main input and a main output of the high voltage divider when the voltage across the power switch is lower than a threshold voltage.
    Type: Application
