Abstract: A controller may predict an estimated occurrence of a high-resistance state of a dimmer, wherein the high-resistance state occurs when the dimmer begins phase-cutting an alternating current voltage signal. The controller may also be configured to operate in a trailing-edge exposure mode for a period of time wherein the period of time includes a time of the estimated occurrence of the high-resistance state in order to allow the controller to detect the occurrence of the high-resistance state, wherein energy is transferred from an input to a dissipative element during the trailing-edge exposure mode. The controller may further be configured to minimize a time between a beginning of the period of time and the estimated occurrence of the high-resistance state by modifying the period of time based on an estimated charging time of a capacitor of the dimmer.
