Abstract
A power supply system includes a rectifier configured to rectify an input signal to generate a rectified signal having a single polarity, a converter configured to generate a drive signal for powering a light source, and a ripple control system including a voltage-controlled resistor (VCR) coupled to a secondary-side of the converter and configured to dynamically adjust a resistance of the VCR to compensate for ripples in the drive signal.

A power supply system comprising:
- a rectifier configured to rectify an input signal to generate a rectified signal having a single polarity;
- a converter configured to generate a drive signal for powering a light source;
- and
- a ripple control system comprising a voltage-controlled resistor (VCR) coupled to a secondary-side of the converter and configured to dynamically adjust a resistance of the VCR to compensate for ripples in the drive signal.

A power supply system comprising:
- a converter configured to generate a drive signal based on a rectified input signal for powering a light source;
- a ripple control system comprising a voltage-controlled resistor (VCR) coupled to a secondary-side of the converter and configured to dynamically adjust a resistance of the VCR to compensate for ripples in the drive signal;
- and
- a voltage threshold controller configured to sense a voltage drop across the VCR and to generate a feedback signal to control the drive signal of the converter based on the voltage drop.
