Abstract

The calculations and measurements are presented of power factor correction and distortion reduction using the peak current programmed boost topology. The topology and a regulator using a dedicated power factor controller are introduced. The input current waveshape is modeled mathematically, and analytical expressions for the calculation of the power factor and total harmonic distortion are derived. Various measurement method are described, and actual data related to the high-power regulator are presented, including pictures of the low-frequency spectrum of the input current. An enhancement circuit is added to the original regulator circuit, and another set of data is taken. Calculated and measured data are summarized and compared to the IEC 555-2 specifications.<>
