A ground power unit based on paralleled interleaved inverters for a More-Electric-Aircraft

In the More-Electric-Aircrafts the role of the power converters is fundamental and in the last years the amount of electric power has increased rapidly. In this paper a power conversion stage is proposed and controlled for the Ground Power Unit of a More-Electric-Aircraft. The power conversion topology is based on paralleled converters with interleaved modulation which allows to overcome constraints due to low ratio between the switching frequency and the fundamental frequency (400 Hz) and to minimize the size of the filtering elements. Simulation results prove the effectiveness of the proposed solution.
