| Title: |
Sinusoidal Inductorless Dimmer Applying Variable Frequency Power Signal in Response to User Command |
| Abstract: |
A control service delivers controlled magnitude energy from a sinusoidal
power source in the form of a sequence of pulses conforming to the
sinusoidal envelope. A gate signal operated at a selected frequency
applies gating pulses to a gating device receiving the sinusoidal power
signal and applying its output to a load. The load receives, at high gate
signal frequencies, substantially all energy presented in the power signal
and, at lower gate signal frequencies, a selected magnitude energy taken
from the sinusoidal power signal. The power applied to the load does not
produce undesirable noise or radio frequency interference and does not
require use of an expensive, heavy and volumous choke or inductor.
