This paper explores new techniques to reduce the conducted EMI generated by switched
power converters operating in multiconverter arrangement. These techniques are based in the
combined application of interleaving and the modulation of some characteristics of the switching
patterns. The effectiveness of such methods in terms of EMI reduction is theoreticaly developed
and experimentally validated in a four channel parallel buck converter operating in closed loop.
The technique that provides the best attenuation results is identified. Finally, undesired sideeffects
produced by these techniques, such as an increase in the output voltage ripple, are
