DN-39E Optimizing Performance in UC3854 Power Factor Correction Applications

Texas Instruments

Published Date: 09/05/1999

Description

The performance of the UC3854 Power-Factor Correction IC in the 250W application example has been evaluated using a precision PFC/THD instrument. The result was a power factor of 0.999 and Total Harmonic Distortion (THD) of 3.81% measured to the 50th line frequency harmonic at nominal line and full load. Users should get similar results at these conditions. as well as over most line and load rang
