2. Filter Design, Layout and Performance
maximum possible reduction of harmonic
disturbances created by the SPS power converters
and the TCR (250 Hz, 350 Hz, 550 Hz, 650 Hz, 850
Hz, 950 Hz and HF)
Goal
Realisation
Harmonic filters for 100 Hz, 150 Hz, 250 Hz,
350 Hz, 550 Hz, 650 Hz, 850 Hz, 950 Hz, 1050 Hz)
