Control circuit for a phase-cut dimmer and a method of controlling a phase-cut dimmer
Abstract:
A control circuit is disclosed for lighting applications having a load and an AC leading-edge phase-cut dimmer comprising a phase-cutting switch, the circuit comprising: a detection circuit for detecting a deadlock state of the dimmer; and an activation circuit configured to, in response to the detection circuit detecting a deadlock state of the dimmer, supply a DC current to the dimmer to exit the deadlock state by activating the dimmer. A method of operating such a control circuit is also disclosed.
Abstract(Chinese):
