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 converterвЂ™s switching frequency to an applied signal by a phase locked loop turning it into a voltage controlled oscillator.
