METHOD AND APPARATUS FOR SYNCHRONOUS SINE WAVE DIMMING OF LUMINARIES
Document Type and Number:
WIPO Patent Application WO/2012/018376
Kind Code:
A4
Abstract:
[0120] A luminary dimming system having a three terminal dimming unit. The dimming unit includes a power controller and a receiver and is responsive to dimming directives received by the receiver. The power controller controls a buck switch and a freewheel switch in a manner that allows reduction of alternating current voltages. Such voltage reduction is accomplished in a manner that preserves the waveform of the source voltage and the power factor exhibited by the luminary.
