| Abstract |
ln standard Power Factor Preregulators (PFP's), there is a trade-off between output voltage dynamic and input current distortion. ln this paper, several control techniques aimed to improve the output voltage transient response of Power Factor Preregulators (PFP's) while maintaining a high power factor are reviewed and compared. These methods do not require additional sensing, but only simple analog circuitry, and work with wide input voltage range. Simulation tests on a Boost converter with average current control highlight merits and drawbacks of each solution. |
