Abstract:
Disclosed is an overcurrent protection circuit for use in a dimmer circuit having a switching device for controlling power delivered to a load. The overcurrent protection circuit comprises means for sensing a load current passing through the load and means for comparing the sensed load current with a threshold, wherein the threshold is a dynamic current threshold. Also disclosed is a dimmer circuit comprising the overcurrent protection circuit.
