Abstract

See full text

A system is described that includes a half-bridge, a first driver, a second driver, and a controller unit. The half-bridge includes a first switch coupled to a second switch at a switching node. The first driver is configured to drive the first switch and the second driver is configured to drive the second switch. The controller unit is configured to determine whether a hard commutation event is likely to occur at the half-bridge during a future switching cycle, and responsive to determining that the hard commutation event is likely to occur during the future switching cycle, control the first driver and the second driver to activate at least one hard commutation countermeasure.
