Abstract

A new technique to reduce EMI in modular power multiconverters is described. The technique is based on a combination of switching frequency modulation and a variable delay between commutation signals of the single converters. The proposed technique has been validated experimentally in a four converters parallel topology. A significant EMI reduction has been obtained with regard to conventional techniques.
