EMI reduction by interleaving of power converters

Switched converters are a source of EMI due to the hard switching and abrupt edges in the current and voltage waveforms. Interleaved converters can reduce the EMI at the source, minimizing the generation of conducted EMI, without changing the normal operation of the circuit. Input filter can be reduced, radiated EMI is lower and internal EMI problems are minimized. This paper is focused on exploring the capabilities of the interleaved converters to reduce conducted EMI, taking into account the non-idealities of the actual converters.
