    PDF, 202 Kb, Datei veröffentlicht: 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, Revision: A, Datei veröffentlicht: 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.
