“…In addition to the two E-field probes, a Solar 7334-1 loop antenna was placed approximately at 7 cm from the cablemount. In [11] the usage of this loop antenna in conjunction with an oscilloscope was discussed, whereas more details can be found about the processing of the received signals in [12]. Its intended operating range is from 30 Hz to 100 kHz.…”

The implementation of all-electric aircraft (AEA) will face several engineering challenges mainly due to its high power requirements. At its core lies the electric powertrain, consisting of the battery, inverter, and motor. Non-ideal behavior of components, cables, and other structures will act as a propagation path for Electroagnetic Interference (EMI). The analysis of EMI in the design phase is considerably complicated due to structural and geometric design, thus, hard to predict. This paper is a first step towards proposing the attenuation of radiated emissions from power feeders by optimizing the switching behavior of converters. Thus, contributing to the overall attenuation level and reducing the performance requirements of power line filters.

“…Comparing I L-N and V DM , shows a deviation of 2 dB, which is relatively large. In case of the current measurement, a load of 250 Ω was assumed to be broadband [65]. Based on the above stated deviations, the voltage port transfer functions were measured to determine if the ratio is indeed 1:50.…”

Remarkably, over the last few decades, the electromagnetic interference within 9 to 150 kHz was especially accentuated since the switching frequency of power electronic converters is still limited to several kHz. Thus, bringing up the debate on regulation. From the point of view of the electromagnetic interference noise shape, two cases represent the extremes of possibilities among the various possible converter control algorithms: the deterministic and pseudo-random modulation.Pseudo-random modulation has been considered a complementary methodology to achieve electromagnetic compatibility, jointly with the electromagnetic interference filters and improvements on the printed circuit board layouts. The pseudorandom modulation methodology has also been utilized as prior-art for the reduction of converter power losses while achieving a target control dynamics or system power density or cost, and/or to achieve a flattening of power efficiency curves as function of processed power, and to improve control dynamics in transient operations. Notwithstanding, the impact of pseudo-random modulation on measured conducted electromagnetic interference is still unclear for the low frequency range.For instance, evaluating any electromagnetic interference noise spreading approach is not apparent once it depends on several pseudo-random modulation parameters, dwell time and resolution bandwidth. The conventional super-heterodyne frequency band stepping EMI test receiver defines the dwell time and the resolution bandwidth. For this reason, historically, pseudo-random modulations have been questioned and accused of being a fraudulent way of passing regulations. Nonetheless, research has been presented over the last decades to support the electromagnetic interference noise spreading approach in practical situations, e.g., with power line communication systems.Thus, the research carried out and presented in this thesis, all in all, proposed pseudo-random modulation control algorithms with a random stream based on different methods. The National Instruments PXI with Field-Programmable Gate Array was used as a cyber-physical platform for fast prototyping. This engineering tool enables the necessary electromagnetic interference investigations. The detail Field-Programmable Gate Array implementation and benchmarking of each studied methods are given. Although pseudo-random modulation methods exist previously to this v VI SUMMARY thesis work, the main novelty of the proposed developments lies in the identification and selection of the most suited random stream method for the problem at hand, and its necessary modification for implementation in a fixed-point processor. In this way demonstrating that it is possible to develop new, dedicated converter control algorithms that allow shaping the spectrum of disturbances to meet standardization or technical requirements.Furthermore, once it has been found that the conventional EMC test based on frequency scanning might not be sufficient to evaluate pseudo-random modulated DC/DC converter appropri...
