Abstract

This paper deals with the analysis of a new implementation of the proposed active input current shaper (AICS). This implementation allows us to use an AICS with DC-to-DC topologies in which the voltage across the transformer is a symmetrical waveform, e.g. half-bridge, push-pull or full-bridge converters. Using this implementation, the size of the AICS inductors can be reduced and even integrated in only one magnetic core. As in the case of other converters with AICS, the new implementation allows us to reduce the line current harmonics in order to comply with the IEC 1000-3-2 specifications, maintaining all the features of the standard DC-to-DC converters (e.g. fast transient response). Finally, four of the proposed topologies has been experimentally tested
