Abstract
Pulse width modulation of a high frequency series of AC current that is delivered to a lighting load(s) in “slices ” of current by a controller device that enables users to dim their loads while minimizing and/or virtually eliminating the externalities associated with current dimming systems.
Claims17
A method of operation for dimming a load through the use of a dimming system comprised of a controller device that has the capability to chop power current to a lighting load into a high frequency series of individual slices of current that can be supplied to a lighting load in response to a control signal without needing to rectify or invert the power current and also without regard to whether a non-polar or uni-polar switching device is utilized.
