In this paper, a new active current balancing method for a light-emitting diode (LED) driver with multichannel outputs is proposed. In the proposed structure, a low-power nonisolated dc–dc converter in series with each LED string is used to regulate the LED string current. Different from conventional active current balancing methods, in the proposed method, the nonisolated dc–dc converters only process...
A three-phase AC/DC converter should extract the pure sinusoidal current from the AC source, and maintain the DC-bus voltage at a demand level when the dc load varies. In this paper, a novel control method is presented to match these requirements. At the AC side, a real-time voltage and current predictive methods are used to reduce the influence of control delay and voltage harmonics, so that AC current...
