Patent abstract
Disclosed is an inductive load detection circuit for detecting the presence of an inductive load on a dimmer circuit. The detection circuit provides for enhanced detection of the inductive load by detecting voltage ringing resulting from a turn-off of a switching element in the circuit. The ringing can be enhanced by providing a faster turn-off rate in an initial period than a turn-off rate in a steady state period.
