    摘要： A dual stage power converter capable of being installing in a one-gang box and powering an LED load is presented. The dual stage converter can include a power factor correction (PFC) stage operating in transition mode and a resonant converter stage operating at a fixed frequency with a fixed duty cycle and dead time. A dimmer input may be included to select a desired luminosity of the LED load. A main controller adjusts the value of the voltage output from the PFC stage in order to maintain the voltage output from the resonant stage at the desired level.

    摘要： A lighting system includes a converter configured to receive a rectified input voltage and to generate an output voltage based on a gate control signal; a PFC controller including a zero-crossing input, and configured to generate the gate control signal to adjust the output voltage of the converter based on a zero-crossing voltage at the zero-crossing input; a zero-crossing delay circuit coupled between an output of the converter and the zero-crossing input, and configured to slow a rate of change of the zero-crossing voltage based on one or more delay control signals; and a channel controller configured to identify a low-load state of the lighting system, and, in response, to generate the one or more delay control signals.

    摘要： A method of driving a light source by a light driver includes measuring a current output signal of the light driver, calculating a percent change in output signal, determining whether the percent change in output signal is greater than or equal to a first threshold, and in response to determining that the percent change in the output signal is greater than or equal to the first threshold, calculating a percent change in reference voltage based on a current reference voltage and a previous reference voltage, determining whether the percent change in reference voltage is less than a second threshold, and in response to determining that the percent change in reference voltage is less than the second threshold, deactivating filtering and averaging of a dimmer signal received from a dimmer for a period of time, and reactivating the filtering and the averaging of the dimmer signal.
