Abstract The possibilities of output voltage quality improvement and EMI reduction using interleaved buck converters are studied in this work. The problem of excessive output voltage ripples arises when the spread spectrum method is applied to single buck converter in order to reduce the level of EMI emissions. The investigation shows that it is possible to significantly reduce ripple only at certain values of maximal duty ratios D. At other D values pulsation magnitude is considerably larger, although in comparison with single buck converter it is still smaller. Interleaving of converters also leads to input conducted noise reduction.
