Abstract

A circuit is described that includes a switch, a switchable clamping element coupled to the switch, and a driver configured to control the switch based at least in part on a driver control signal. The driver is further configured to enable or disable the switchable clamping element. The switchable clamping element is configured to clamp a voltage across the switch when the switchable clamping element is enabled by the driver and when the voltage across the switch or a current at the switch satisfies a threshold for activating the switchable clamping element.
