Improving the Dimming Performance of Low-Power Single-Stage AC-DC HBLED Drivers

The design of efficient single-stage high-brightness light-emitting diodes (HBLEDs) ac-dc drivers with power factor correction (PFC) in low-power applications is addressed in this paper. The PFC is achieved by using a switching converter with both step-up and step-down voltage capability. It is well...
