  • Solid-state light emitter power supplies, dimmable solid-state light sources, and method of powering solid-state light emitters
    Patent number: 11785688
    Abstract: A solid-state light emitter power supply includes a first rectifier circuit, a second rectifier circuit, a power factor correction (PFC) stage, a first flyback converter, a second flyback converter, and a microcontroller. The rectifier circuits are configured to receive phase-cut signals from respective dimmer circuits as inputs and output respective phase-cut rectified power signals. The PFC stage is configured to receive a sum of the phase-cut rectified power signals as input and output a power-factor corrected electrical power to the flyback converters. The flyback converters are connected in parallel and are configured to power respective loads including a respective solid-state light emitter. The microcontroller is configured to receive signals derived from the phase-cut signals as inputs and to output respective pulse-width modulation (PWM) control signals to each of the flyback converters.
