Impact of Periodic Frequency Modulation on Power Quality of Switching Power Converter

2014 Journal of Electrical and Electronics Engineering  
In this paper power quality of switching frequency modulated (SFM) power converters is analyzed in details. Careful attention is paid on the effect of SFM parameters on switching power converter input current total harmonic distortion (THD) and power factor. Theoretical analysis, simulations and experiments show that SFM used for electromagnetic interference reduction in switching power converters has almost invisible impact on input current THD and power factor of conventional switching power
