Abstract :
The inductor design of a continuous mode boost PFC circuit is usually straight forward but the choice of the variables that decide the size of this inductor is always difficult to quantify and they depend heavily on the designers choice. This paper explores the effect of these variables on the overall performance of the converter, by making extensive measurements of conducted EMI, inductor temperature rise and converter efficiency. Three inductance design values are compared and verified with measurements on a 1200 W prototype operating at about 70 kHz. Based on these measurements, a systematic design approach is suggested
