Abstract

IEC 1000-3-2 regulations impose a reduced harmonic content on any converter with an input power higher than 75 W. However, if the power architecture of the system is based on small on board converters, and the total power is higher than 75 W, IEC regulations must be fulfilled although each individual converter need not comply with the regulations. In this paper, one of the different possible solutions is presented. Each on board converter has an active input current shaper (AICS) in order to reduce the input current harmonic content of each converter and hence, to comply with IEC 1000-3-2 regulations. Moreover, two different types of AICS were compared: the conventional one and a new type of AICS based on a full wave rectifier
