  • UCC28517 100-W PFC power converter with 12-V, 8-W bias supply, Part 2
    PDF, 224 Kb, 档案已发布: Feb 28, 2005
    To conclude the review of the UCC28517 PFC supply, this article covers the design of the second 12-V, 8-W power stage to be used as an auxiliary bias supply.
  • UCC28517 100-W PFC power converter with 12-V, 8-W bias supply, Part 1
    PDF, 202 Kb, 档案已发布: Feb 28, 2005
    Power factor corrected (PFC) preregulators are generally used in ac/dc converters operating above 75 W or to meet line harmonic requirements. This article reviews the design of a 100-W ac/dc power stage with PFC.
  • A New Synchronization Circuit for Power Converters (Rev. A)
    PDF, 209 Kb, 修订版: A, 档案已发布: Apr 21, 2010
    The synchronization of multiple PWM and PFC controllers is desirable for many reasons. The most common reason is that it keeps all the noise at one particular frequency and makes it easier to filter. The circuit described changes the slope of the ramp to lock the converter’s switching frequency to an applied signal by a phase locked loop turning it into a voltage controlled oscillator. Furthermore
