Abstract
A semiconductor switching circuit associated with a power semiconductor circuit is described. The semiconductor switching circuit includes a snubber circuit comprising a snubber switch element that comprises a first terminal configured to couple to a supply node associated with the power semiconductor circuit and a second terminal configured to couple to a switch node associated with the power semiconductor circuit. In some aspects, the snubber switch element is configured to bypass a ringing voltage at the switch node associated with the power semiconductor circuit to the supply node associated with the power semiconductor circuit. In some aspects, the ringing voltage at the switch node comprises a voltage that is greater than a supply voltage associated with the supply node.
