  • Sinusoidal inductorless dimmer providing an amplitude attenuated output
    Patent number: 5365148
    Abstract: A dimmer control circuit for application to a load bank produces a sinusoidal power wave form exhibiting the desirable characteristic of suitable rise and fall times producing little or no audible or radio frequency interference. A pair of MOS-FET power devices operate in a linear mode and attenuate respective half-cycles of a single phase power line as a function of a dimmer control signal applied thereto. The device includes a mechanism for avoiding damage to the power MOS-FET by controlling conditions under which a signal change is applied to the gates of the MOSFETs, and by imbalanced attenuation between the MOS-FETs through the range of the dimmer control signal.
