A PFC Single-Coupled-Inductor Multiple-Output LED Driver Without Electrolytic Capacitor
Meanwhile, to improve the converter efficiency, the energy flow of the converter is optimized with an inductor current programming technique. Finally, the proposed electrolytic capacitor-less PFC SIMO LED driver is developed, designed, tested and compared with a single-stage SIMO design without active power decoupling.

Figure 3. A Common AC/DC Power Supply Block Diagram. The boost PFC has three operation modes based on the inductor current waveform shape: Discontinuous Conduction Mode (DCM), Critical Conduction Mode (CrCM) and Continuous Conduction Mode (CCM). The CrCM is also referred as Transition Mode (TM) in some literature.
