Understanding Power Factor and Input Current Harmonics in Switched Mode Power Supplies
By Alan Gobbi, TDI Power
The proliferation of AC-DC switched mode power supplies has resulted in strict limits being imposed on AC input current power factor and harmonic content. The electronic system designer must take these into account in developing hardware requirements. A sound understanding of typical power factor correction circuit performance and dynamics as a function of line and load will aid in this task.
