Abstract :
To achieve higher power density, power converters are operating at higher switching frequencies. For the high switching frequency operating, not only the efficiency, but also the EMI performance is a big concern. In this paper, based on the developed EMI noise model, switching frequency impact on the single-switch CCM PFC is analyzed and evaluated. Switching frequency selection guideline is given.
