Abstract
An apparatus comprises an energy transfer device configured to supply power from a primary side of an isolation barrier through the isolation barrier to a secondary side of the of the isolation barrier for driving a gate of a switch for controlling output of the switch at the secondary side. The apparatus comprises a monitoring component. The monitoring component is configured to monitor an operating state of the switch. The monitoring component 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.
