Observations of radiated and conducted emissions from an Electric Plane charging station

The paper reports a set of radiated and conducted emissions recorded at an electric airplane's charging station located in Sweden. The measurement exercise undertaken shows the existence of supraharmonic frequency components exceeding the IEC 61000-2-2 limits in the frequency range 129 to 147 kHz. These components are visible in the radiated emissions recorded at the test site as well. Observations of the measured common mode current offer a possible explanation for the radiated magnetic field recorded at the test site in the sub 150 kHz band.
