“…According to Parseval's theorem, the sum (or integral) of the squares of a function is equal to the sum (or integral) of the squares of its transform. Consequently, the record mean power (RMP) has been calculated for all records in the (4.5-8) MHz frequency range according to (2), where N ss is the number of FFT points in the record spectrum, i is the index of the FFT point in the record spectrum, and v is the value of the FFT point. shows the direct relationship between the motorcycle's velocity and the corresponding RMP of the radiated emissions.…”

Abstract-Current automotive electromagnetic compatibility (EMC) standards do not discuss the effect of the driving profile on real traffic vehicular radiated emissions. This paper describes a modeling methodology to evaluate the radiated electromagnetic emissions of electric motorcycles in terms of the driving profile signals such as the vehicle velocity remotely controlled by means of a CAN bus. A time domain EMI measurement system has been used to measure the temporal evolution of the radiated emissions in a semi-anechoic chamber. The CAN bus noise has been reduced by means of adaptive frequency domain cancellation techniques. Experimental results demonstrate that there is a temporal relationship between the motorcycle velocity and the radiated emission power in some specific frequency ranges. A Multilayer Perceptron (MLP) neural model has been developed to estimate the radiated emissions power in terms of the motorcycle velocity. Details of the training and testing of the developed neural estimator are described.

“…Firstly, the interference source feature of MOSFET is discussed. The time domain on-off processes of MOSFET can be described as trapezoidal pulses [18]. Assuming the turn-on time is the same with the turn-off time, the trapezoidal pulses will have the same rising and dropping edges.…”

Abstract-Electromagnetic interference (EMI) of the power supply system in electric vehicles will seriously affect the safety of the vehicle and passengers' health. So a model of power supply system is presented to analyze its conducted EMI in the paper. This model shows the effects of paralleled interleaving DC/DC converter, which contains the new circular current EMI characteristics. Also, a novel power battery model is established considering both the energy dynamic processes and the high frequency features. Firstly, the power electronics devices are studied as the most important part of the DC/DC converter. Then, the equivalent model of the paralleled interleaving DC/DC converter is set up to express the interference source features. Also, the power battery, which is the main energy storage equipment in electric vehicles, is modeled as EMI propagation paths. Furthermore, loads of the power supply system, such as lead acid battery and low voltage devices, are investigated to evaluate their immunity. Finally, the system model is established. The system EMI is analyzed to get their generating causes, time domain and frequency domain characteristics based on both simulations and experiments.

Abstract-This paper presents a comprehensive analysis of the roadway powering system for electric vehicles (EVs) and proposes a design from the perspective of power track design, integration, and powering control strategy, aiming to ensure the charging power and persistence, enhance the control flexibility, and reduce the construction cost. 1) A novel design scheme is first proposed to determine the length and number of turns for power tracks by investigating the power supply-and-demand and the loss. 2) A novel evaluation index, namely the magnetic distribution variance, is proposed to determine the gap between adjacent tracks, which can effectively produce evenly-distributed energy field, thus improving the dynamic charging performance for EVs. 3) A sectional powering control strategy is proposed to implement a cost-saving and flexible roadway powering system. Lastly, the simulated and experimental results show that the exemplified prototype can achieve the transmission power 50 W over the distance of 200 mm, which verifies the proposed EV dynamic charging system with the salient advantages of the constant energization, flexible power control, and cost saving.
