Abstract

See full text

In a general aspect, an ignition circuit can include a control circuit that is coupled with an engine control unit (ECU) to receive a command signal from the ECU. The control circuit can include a multi-pulse generator configured to, in response to the command signal, generate a multi-pulse drive signal. The multi-pulse drive signal can include a first pulse cycle having a first duty cycle, a second pulse cycle having a second duty cycle, and a dwell period during which the multi-pulse drive signal continuously remains at a logic high value. The control circuit can be configured to provide the multi-pulse drive signal to an ignition switch coupled with the control circuit to receive the multi-pulse drive signal.
