| Abstract |
In this paper, a single-stage flyback converter is operated as a single-phase ac-dc converter with active power factor correction. The input filter required to reduce the differential mode conducted emissions is examined, and modulation of the switching frequency is suggested as a means of minimising the filter requirements. Various modulation strategies are studied and a simple analogue circuit implementation is presented for the optimum strategy. The influence of component tolerances on
harmonic distortion is also investigated. |
