Abstract: A lighting driver includes a negative third harmonic generator configured to generate a negative third harmonic signal corresponding to a third harmonic of an AC input voltage shifted by 180 degrees. The lighting driver further includes an adder circuit configured to generate an adder output signal by adding the negative third harmonic signal to a voltage divider output signal generated from the AC input voltage. The lighting driver also includes a controller configured to control generation of a DC output voltage provided by the lighting driver based on a control signal generated from the adder output signal.
