  • Converting dimmer switch AC output duty cycle variation into amplitude variation
    Patent number: 8344647
    Abstract: A method of adapting the output of commercially available dimmer switches for use with non-incandescent light sources. Commercially available TRIAC and SCR based dimmers (62) output a waveform where AC output is varied based on user input by adjusting duty cycle (71), or the portion of the AC waveform that is output to the electrical load (76), having undesirable effects on non-incandescent loads. This output is fed into two alternately charging and discharging energy storage devices (72, 75), generating a modified AC waveform whose amplitude is proportional to the duty cycle percentage of the incoming AC waveform from the dimmer. Charge and discharge switching is handled by two switches (73, 74), triggered by the natural oscillation of the incoming AC waveform.
