Exploring interleaved converters as an EMI reduction technique in power converters

Switched mode power supplies are widely used due to their advantages on efficiency, size and weight. However, it is necessary to include an EMI filter that is not always considered, but affects the overall volume. This paper quantifies the advantages of the interleaved converters from the point of view of EMI generation. Clear benefits are obtained and a great reduction of the EMI filter is achieved.
