Abstract
A ripple reduction circuit is provided. The ripple reduction circuit may include a ripple capacitor configured to drive at least a first segment of a string of light emitting diodes (LEDs), a first diode having an anode coupled to the ripple capacitor, and a cathode configured to be coupled to an input end of the first LED segment, a second diode having a cathode coupled to the ripple capacitor and the anode of the first diode, and an anode configured to be coupled between the first LED segment and a second LED segment of the string of LEDs, a third diode having an anode coupled to the ripple capacitor, and a cathode configured to be coupled to a last LED segment of the string of LEDs, and a fourth diode having a cathode coupled to the ripple capacitor and the anode of the third diode.
