| Abstract |
The Single Ended Primary lnductance Converter (SEPIC) presents several advantages over boost and flyback topologies which makes this converter very convenient to be used as a Power Factor Preregulator (PFP). Due to this fact, the PWM SEPIC used as PFP is studied in this paper. Stress in compo,nents and operation in continuous and discontinuous conduction mode are considered in thios paper. The study reveals that both types of PFP control (multiplier approach and voltage-follower approach) can be used in PWM SEPIC, the first one when it operates in continuous mode and the second one when it operates in discontinuous conduction mode. Finally, the theoretical analysis is validated in two prototypes (continuous and discontinuous conduction mode). |
