“…The high-frequency link matrix converter (HFLMC) is a single-stage bidirectional and isolated AC-DC energy conversion system [16]. The new modulation proposed in [17] and patented in [18] allows independent control of active and reactive power (PQ control) as well as the DC current in the battery pack. By exploring the MC attributes, circuit volume and weight can be reduced, and a longer service life is expected when compared with equivalent DC-link based solutions [16,19,20].…”

This paper describes the design of an electromagnetic interference (EMI) filter for the high-frequency link matrix converter (HFLMC). The proposed method aims to systematize the design process for pre-compliance with CISPR 11 Class B standard in the frequency range 150 kHz to 30 MHz. This approach can be extended to other current source converters which allows time-savings during the project of the filter. Conducted emissions are estimated through extended simulation and take into account the effect of the measurement apparatus. Differential-mode (DM) and common-mode (CM) filtering stages are projected separately and then integrated in a synergistic way in a single PCB to reduce volume and weight. A prototype of the filter was constructed and tested in the laboratory. Experimental results with the characterization of the insertion losses following the CISPR 17 standard are provided. The attenuation capability of the filter was demonstrated in the final part of the paper.

“…In industrial applications, ac‐ac power conversion is generally achieved using direct ac‐ac converters, dc‐linked indirect ac‐dc‐ac converters, and matrix converters (MCs) . Despite having a simple structure and control, many direct ac‐ac converters lack the ability to perform full variable frequency operation.…”

Summary A matrix converter (MC) is a topology for ac‐ac power conversion that has been widely investigated and compared with conventional ac‐dc‐ac topologies because of its attractive features. The MC is formed of controlled active devices and does not include any sizeable passive components. The converter can be used to directly control single/three/multiphase loads. MCs are highly effective in controlling the power factor and providing sinusoidal input and output currents. This paper provides a comprehensive state of the art review of the MC and discusses the main topology variations including single‐phase conventional and isolated MCs, three‐phase direct and indirect MCs, impedance source (Z‐source) MCs, multiphase MCs, and multilevel MCs (MMCs). The aim of this research article is to provide a one‐stop information on single/three/multiphase matrix, Z‐source matrix, and multilevel MCs for potential readers, researchers, and practicing engineers.

Control strategies considering the reactive power control are applied to single-phase chargers [15][16][17][18] and to three-phase chargers [19,20]. Charging/discharging with constant current or a constant voltage strategy are considered in Reference [21].…”

Control Strategy for Electric Vehicle Charging Station Power Converters with Active Functions

Based on the assumption that vehicles served by petrol stations will be replaced by Electric Vehicles (EV) in the future, EV public charging station facilities, with off-board fast chargers, will be progressively built. The power demand of these installations is expected to cause great impact on the grid, not only in terms of peak power demanded but also in terms of power quality, because most battery chargers behave as non-linear loads. This paper presents the proposal of a novel comprehensive global control strategy for the power electronic converters associated with bidirectional three-phase EV off-board fast chargers. The Charging Station facility Energy Management System (CS-EMS) sends to each individual fast charger the active and reactive power setpoints. Besides, in case the charger has available capacity, it is assigned to compensate a fraction of the harmonic current demanded by other loads at the charging facility. The proposed approach works well under distorted and unbalanced grid voltages. Its implementation results in improvement in the power quality of each fast charger, which contributes to improvement in the power quality at the charging station facility level, which can even provide ancillary services to the distribution network. Simulation tests are conducted, using a 100 kW power electronic converter model, under different load and grid conditions, to validate the effectiveness and the applicability of the proposed control strategy.
