Abstract :
Booster DC to DC converters operating with 20 kHz conversion frequency perform rapid regulation that make them very well suited to use as active filters for attenuation of low frequency noise. Booster converters with such filtering qualities are beeing used in a new series of 48 V DC power plants. The noise on the output is kept well below the limits that are specified in the CCITT-recommendations.
