Abstract:
A method for controlling an active snubber circuit includes measuring a gate voltage at a first transistor and measuring a gate voltage at a second transistor. The method also includes determining whether the first transistor and the second transistor are in the same state based on the gate voltage measured at the first transistor and the gate voltage measured at the second transistor. The method also includes, in response to a determination that the first transistor and the second transistor are in the same state, enabling the active snubber circuit. The method also includes, in response to a determination that the first transistor and the second transistor are not in the same state, disabling the enable signal. The method also includes disabling the active snubber circuit in response to the enable signal being disabled.
