The limited switching frequency, size and weight concerns, and the stringent limits for the injected grid current harmonics challenge the implementation of LCL grid filters for low-voltage multi-megawatt (multi-MW) renewable energy converters. Traditional design procedures of such filters employed in low power and high switching frequency converters may not hold for a multi-MW filter interfacing a...
The proposed increase of power electronic subsystems for More Electrical Aircraft (MEA) brings severe challenges to aircraft power distribution. Current aircraft power systems work at a fundamental frequency of 400 Hz while proposed AC MEA power networks for next generation aircrafts will have a fundamental frequency which varies most probably between 360 and 900 Hz. An active shunt filter (ASF) is...
