Abstract :
In general, the input current of an AC/DC electronic converter contains a considerable number of harmonics. To reduce the harmonic effects within levels allowed by a future norm, the IEC555-2, a preconditioner based on a switched mode power supply can be used. But the employment of a preconditioner or power factor corrector may cause undesirable HF-distortion and dissipation. This paper describes two preconditioners and in addition, presents measurements for the purposes of comparison of electromagnetic compatibility (EMC)
