摘要： A solid-state lighting system comprises a plurality of light-emitting devices (e.g., light-emitting diodes) and an alternating current to direct current (AC-DC) converter that converts AC power to DC power for powering the plurality of light-emitting devices. The AC-DC converter is configured to perform AC -DC conversion directly, without the need for or use of a bridge rectifier or step-down transformer. According to one aspect of the invention, the light-emitting devices of the solid-state lighting system are autonomous and individually powered by a plurality of DC power supplies generated from the DC power produced by the AC-DC converter. According to another aspect, a plurality of phase-offset dimmer control signals are generated based on waveform distortions in a dimming signal produced by a conventional dimmer switch. The phase-offset dimmer control signals are used to individually control the dimming of the light-emitting devices.

摘要： An AC/DC converter that converts an AC input voltage Vin to a DC output voltage comprises an inductor, a capacitor selectively coupled to the inductor, a plurality of switches, and a controller. The controller configures the plurality of switches, inductor, and capacitor to operate as a buck converter during times when Vin > Vout and to operate as an inverting buck converter during times when Vin

摘要： Methods and apparatus for translating duty cycle information in duty-cycle- modulated signals to higher frequencies or higher data rates. An exemplary duty cycle translator includes a duty cycle evaluator, a high-speed digital counter, and a comparator. The duty cycle evaluator generates a first digital number representing a duty cycle of a low-frequency input duty-cycle-modulated (DCM) signal. The comparator compares the first digital number to a second digital number generated by the high-speed digital counter, and generates, based on the comparison, an output DCM signal having a higher frequency or data rate than the frequency or data rate of the low- frequency input DCM signal but a duty cycle that is substantially the same as the duty cycle of the low- frequency input DCM signal.
