“…CM currents can produce high field-strength values when magnetic field measurements are made. Figure 9 shows, in accordance with [9,10], the block diagram of a WPT system in an absorber-lined shielded enclosure (ALSE) and the resulting interference paths due to the parasitic capacitances. For the EMC test in an ALSE, the WPT system is mounted on an insulating pad which is 5 cm high and placed on a conductive copper ground plane.…”

To increase the acceptance of electric vehicles (EVs), inductive charging technology can be an important tool because of the simplified charging process for the user. This paper presents the fundamentals of wireless power transfer (WPT) for EVs, while focusing on electromagnetic compatibility (EMC). This work deals with the investigation of the conducted and field-bound interference emissions using a WPT system with a max. input power of 3.6 kW. During the research, a new frequency-tracking algorithm is developed, to find the optimal operating frequency at any coil misalignment. The impedance behavior as well as the possible interference paths are investigated, showing the great geometric influence of the test bench setup. The conducted interference currents are analyzed and subsequently filtered. The filter shows good performance in attenuating common mode currents. The measured radiated magnetic field is directly rated against the proposed limits of various standards. Finally, the EMC influence of the direct current (DC) power supply line to the inverter is examined, which is not defined precisely in the standard. This underlines the significance of a standardized test setup, since the limit values can be met under different geometric circumstances of the DC cable.
