| Title: |
Paired Dimmers for Controlling Harmonic Currents |
| Abstract: |
A control system for a plurality of switched loads includes an AC line and
a neutral wire and a pair of loads coupled in parallel between the AC line
and the neutral. The switched loads may be operated so that one load in
the pair operates in forward phase control mode and the other load in the
pair operates in reverse phase control mode. This reduces harmonic current
in the neutral wire otherwise resulting from odd order harmonics generated
by the switching of AC current into the load during normal operation.
