How to Specify the Current Sense Resistor in a Converter Using the UCC28083 - 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.
