Impact of flat-top voltage waveform distortion on harmonic current emission and summation of electronic household appliances

Electronic household appliances are non-linearloads and emit harmonics into the low voltage networks.Usually, these loads are simply modelled by constantcurrent source models, which only represent the harmonicemission of the appliances for a single supply voltagedistortion, mostly sinusoidal conditions.Measurements have shown that the harmonic currentsemitted by electronic devices can significantly depend onthe circuit topology and the existing supply voltagedistortion. This paper studies the impact of supply voltagedistortion, which can be typically found in public lowvoltage networks (so-called flat-top voltage waveform), onthe harmonic current emission of individual devices withdifferent circuit topologies as well as the impact of supplyvoltage distortion on the harmonic summation of thesedevices.<p>Konferensartikel i tidskrift
