Abstract:
A system and related techniques for dimming a solid-state light source are disclosed. The system may be configured to dim the output of a solid-state emitter via a combination of phase-cut dimming and high-frequency pulse-width modulation (PWM) dimming. To this end, the system may include a digital rectification module configured to generate a rectified DC power and a rectified phase-cut signal based on a phase-cut AC signal received from a phase-cut dimmer. The system further may include a microcontroller unit (MCU) configured to measure the duration of low and high states of the rectified phase-cut signal using zero-crossing digital phase-cut detection and output PWM signal(s) based, at least in part, on those measured values. The rectified DC power and PWM signal(s) may be delivered to a DC-to-DC converter, which may output DC power(s) having an intensity based on the rectified DC power and PWM signal(s), causing receiving emitter(s) to dim.
