Abstract-There are serious electromagnetic compatibility (EMC) problems in electric vehicles. In order to explain and solve them, a systematic method to analyze conducted interferences of the electric drive system is shown in this paper. This method represents the effects of the power battery which is the most different part between electric drive systems used in electric vehicles and other cases. Also, equivalent models are established from power electronics devices to the entire system by considering both the working mechanism and stray parameters. Firstly, insulated gate bipolar transistor (IGBT) and inverter are studied as the main interference source. A new expression is put forward to estimate the frequency domain features of the inverter disturbances. Then, power battery and electric motor are discussed as the main propagation paths. Their high frequency circuit models are given with parameters obtained from tests and measurements. Finally, the system model is established. The system interferences are analyzed to get their generation causes, influence factors and frequency domain characteristics. Comparisons between simulations and experiments verify the correctness of the models and the method.

“…The coupling of the FE and BIE formulations is done by expressing the continuities of the magnetic vector potential and of the tangential component of the magnetic field on the airgap interfaces. The consideration of the Dirichlet boundary condition on the external stator outline leads to a nonlinear system of equations solved using the Newton-Raphson algorithm [16,17]. The hybrid coupling method is applied to the calculation of the magnetic field in the proposed BLDC machine, and the obtained results for magnetic field in aligned, unaligned and half-aligned are 0.974, 0.357, and 0.687 Tesla, respectively.…”

Abstract-This paper deals with electromagnetic design and threedimensional (3-D) magnetic field analysis of a novel configuration brushless DC (BLDC) field assisted machine based on a hybrid analytical and 3-D finite element method (FEM) analysis. The aim of this hybrid design method is improving the accuracy and computation time for presented complex magnetic structure. In this hybrid design methodology obtained primary magnetic and electric characteristics including magnetic flux density, flux linkage and induced Back-EMF profile for studied configuration are verified by 3-D FE computation. Comparison of the calculated magnetic field and terminal voltage characteristics by their requested values and obtained values illustrates the conformity of the designed parameters. In this study in order to determine the optimum operation, geometry parameters of the proposed machine are optimized based on multi-objective optimization design and genetic algorithm, and finally 3-D FEM verification is coupled by boundary integral equation method (BIEM). Additionally, the accuracy of 3-D FE analysis is verified by comparing the calculated results with the experimental measured values.

The DC/DC converter is the core part of the two-stage electric vehicle Onboard Charger. At present, the phase-shifted full-bridge soft-switching DC/DC converter has problems such as difficulty in commutation of the lagging leg, voltage fluctuation on the secondary side of the transformer, and low efficiency. A full-bridge DC/DC converter with two clamp diodes and synchronous rectification is proposed in this paper. Clamping diodes are used to suppress the voltage oscillation of the secondary side of the transformer and provide the commutating energy of the lagging leg. Synchronous rectification reduces the loss of the switching device. The operating principle and control method of the DC/DC converter are analyzed, and the switching device loss is calculated. The simulation and experimental results show that, compared with the traditional DC/DC converter, the voltage impulse of the secondary side of the transformer is smaller, the efficiency is higher, and the soft switch can be realized in a wide load range, which satisfies the requirement of fast charging of vehicle-mounted batteries.
