The effects of active power electronics on the higher frequency grid impedance up to 150 kHz

Bernhard Grasel, Jose Baptista, Manfred TragnerUniversity of Applied Sciences Technikum Vienna, University of Vila Real Portugal, NEO Messtechnik GmbH MotivationDC charging stations for electric vehicles use active power electronics to convert alternating current to direct current, which causes supraharmonic emissions (SH) in the frequency range of 2–150 kHz [1], [2]. To achieve high efficiencies, high […]
