Claim of US Patent No. 11,116,052


1. A method of controlling a power supply by a power supply controller electrically coupled to a dimmer, the method comprising:sampling, by a processor of the power supply controller, a signal corresponding to dimmer levels of the dimmer to generate a plurality of sample values;
determining, by the processor, whether there is a change in the dimmer levels based on a current sample value of the plurality of sample values;
determining, by the processor, a dynamic weight of the current sample value based on the determining whether there is a change in the dimmer levels;
filtering, by the processor, the plurality of sample values based on the dynamic weight to generate a plurality of filtered values; and
generating, by the processor, a control signal based on the filtered values for transmission to the power supply, the power supply being configured to drive a light source based on the control signal.
