Abstract: A power switch assembly comprises a power switch, a driving circuit configured to control the power switch, a protection device having a first current duration and a first current value and arranged between the driving circuit and the power switch, the protection device being configured to decouple the driving circuit from the power switch based on the first current duration and the first current value, and a clamping device having a second current duration and a second current value and arranged between the driving circuit, the protection device and the power switch, the clamping device being configured to couple the power switch to a second assembly load terminal of the power switch assembly based on the second current duration and the second current value. The first current duration is longer than the second current duration. The first current value is lower than the second current value.

Abstract: An apparatus comprises a power source connected to a buffer capacitor. The apparatus comprises a first switch connected between the buffer capacitor and a driven switch. The buffer capacitor is charged by the power source when the first switch is turned off. The apparatus comprises a comparator. The comparator monitors the charging of the buffer capacitor. In response to the buffer capacitor reaching a threshold amount of charge, the comparator turns on the first switch to initiate a charge redistribution of charge from the buffer capacitor to the driven switch.

Abstract: An apparatus comprises an energy transfer device (200) configured to supply power from a primary side (202) of an isolation barrier (208) through the isolation barrier (208) to a secondary side (216) of the of the isolation barrier (208) for driving a gate of a switch (212) for controlling output of the switch (212) at the secondary side (216). The apparatus comprises a monitoring component (222). The monitoring component (222) is configured to monitor an operating state of the switch (212). The monitoring component (222) is configured to evaluate the operating state to determine whether a fault has occurred, perform a countermeasure, and/or provide a signal of the fault.
