“…The voltage-source inverter (VSI) converter generates three switching voltages (V XO , V YO , V ZO ) causing the common-mode voltage V MC , whose equation is given in (1). To reduce the variations of the common-mode voltage ( Figure 1.b), modulation strategies have been developed and are based on the synchronization of two opposite commutations of two legs [2], [4], [5] (Figure 2).…”

“…They can also operate in rectifier mode when the vehicle is braking and energy is being recovered to the battery. The use of these kinds of converters is a source of electromagnetic compatibility (EMC) problems, mainly because of the generated common-mode voltage whose variations excite stray capacitances [1] between cables, motors, power converters and the ground. This excitation is the source of a high frequency current, named common-mode current, which causes EMC issues.…”

In the simulation of power electronics systems, for reasons of computing time and convergence, it may be necessary to use ideal components which generate ideal voltage switchings (steep edges). However, in reality, these voltage variations are far from ideal and to reproduce a voltage closer to reality, it is necessary to model these variations. This is especially important for the study of residual voltage obtained by simultaneous switching, which are present in PWM strategies developped to reduce the impact of the common-mode voltage generated by 3-phase inverters. This paper is focused on the required model accuracy, in order to take into account these residues obtained by the synchronization of switching voltages.

In the BLDC motor-drive system, the leakage current from a motor to a ground network and existence of high-frequency components of the DC link current are the most important factors that cause conducting interference. The leakage currents of the motors, flow through common ground, will interfere with other equipment because of the high density of electrical and electronic systems in the spacecraft and aircrafts. Moreover, generally there are common DC buses in the mentioned systems, which aggravate the problem. Function of the electric motor causes appearance of the high-frequency components in the DC link current, which can interfere with other subsystems. In this paper, the analysis of electromagnetic noise and presentation of the proposed method based on the frequency spectrum of the DC link current and the leakage current from the motor to the ground network are done. The proposed method presents a new process based on the filtering method to overcome EMI. To cover the requirement analysis, the Maxwell software is used.

“…Also, the produced common mode voltage in motor terminals is the reason of leakage current. High value of dv/dt is also responsible for CM EMI as identified in [1][2][3]. On the other hand, High di/dt may result in differential mode (DM) EMI [4,5].…”

High reliability and low electromagnetic interference (EMI) are two important factors for many industrial applications such as air based electric transport system charger (AETSC). Therefore, it is essential to introduce high reliability and low EMI power converters. This paper presents a new high reliability and low current ripple DC-DC converter. For the proposed converter, a spectrum analysis approach for suppressing the EMI using chaotic sinusoidal pulse width modulation is provided. In addition, the proposed converter has radio frequency (RF) EMI lower than 100 kHz. However, for higher than 100 kHz, EMI issue of the proposed converter has unsuitable situation. 1. NOMENCLATURE A: amplitude of signal, f c : carrier signal, υ m (τ): unitary amplitude of modulated signal, k ω : a controlled factor, T C : the main frequency of switch which is a constant, x n : the nth output of chaotic mapping, β: a modulation factor.
