On 10. July 2025

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 […]

Impact of Electrical Equipment on Frequency-Dependent Grid Impedance up to 150 kHz

Posted by Harald
On 18. February 2025

Direct current charging stations for electric vehicles or photovoltaic inverters or heat pumps use active power electronics to convert alternating current to direct current. High switching frequencies (IGBT) are used for the DC or AC conversion in order to achieve the lowest possible switching loss and therefore the highest possible efficiency. Switching frequencies of 10 […]

Superharmonic disturbances in the distribution grid – New video

Posted by Neo Messtechnik
On 11. December 2024

The frequency ranges of superharmonic voltages and currents are only considered to a limited extent or limited in the applicable power quality standards for the distribution grid. In fact, however, they occur mainly in connection with feeders or also charging stations and lead to disturbances in the grid.In this video, we measure and evaluate superharmonic […]
