Abstract

A driver may comprise a first node, a second node, and processing circuitry. The first node is configured to receive a command from controller circuitry. The second node is configured to receive a commutation signal for activating or deactivating a switch. The processing circuitry is configured to determine, based on the received command, an activation setting for an activation characteristic for the switch and a deactivation setting for a deactivation characteristic for the switch and drive the switch based on the commutation signal. To drive the switch, the processing circuitry is configured to change, at a first time, the deactivation characteristic for the switch from a previous deactivation setting to the determined deactivation setting and change, at a second time that is different from the first time, the activation characteristic for the switch from a previous activation setting to the determined activation setting.
