Volumetric optimization of passive filter for power electronics input stage in the more electrical aircraft

The increasing number of power electronic converters connected to aircraft electrical supply networks increases the harmonic levels. Conventional filter design is not well adapted to many power converters, since their behaviour is strongly coupled with filter values. This paper proposes a methodology to optimize a passive input filter and to fulfil harmonic and power factor standards. The method is applied to a diode rectifier, with capacitive load, which represents a very common power input stage for actuators.
