“…The q-axis current i q , instead, is typically controlled to compensate the reactive power injected by the filter capacitors C f (i.e., to ensure unity power factor operation at the PCC), nevertheless it can be set to any value that complies with the converter-side power factor angle limitations of the rectifier (see Section 2.4), being ϕ = tan −1 (i q /i d ). Finally, the DC-link mid-point voltage balancing loop ensures V pm ≈ V mn at all times, acting on the zero-sequence voltage v o injection [9,[14][15][16]51]. In particular, this control loop theoretically does not interfere with the others, as v o affects neither the active power transfer nor the phase current formation process (see Section 2.1.1).…”

Three-phase three-level unidirectional rectifiers are among the most adopted topologies for general active rectification, achieving an excellent compromise between cost, complexity and overall performance. The unidirectional nature of these rectifiers negatively affects their operation, e.g., distorting the input currents around the zero-crossings, limiting the maximum converter-side displacement power factor, reducing the split DC-link mid-point current capability and limiting the converter ability to compensate the low-frequency DC-link mid-point voltage oscillation. In particular, the rectifier operation under non-unity power factor and/or under constant zero-sequence voltage injection (i.e., when unbalanced split DC-link loading occurs) typically yields large and uncontrolled input current distortion, effectively limiting the acceptable operating region of the converter. Although high bandwidth current control loops and enhanced phase current sampling strategies may improve the rectifier input current distortion, especially at light load, these approaches lose effectiveness when significant phase-shift between voltage and current is required and/or a constant zero-sequence voltage must be injected. Therefore, this paper proposes a complete analysis and performance assessment of three-level unidirectional rectifiers under non-unity power factor operation and unbalanced split DC-link loading. First, the theoretical operating limits of the converter in terms of zero-sequence voltage, modulation index, power factor angle, maximum DC-link mid-point current and minimum DC-link mid-point charge ripple are derived. Leveraging the derived zero-sequence voltage limits, a unified carrier-based pulse-width modulation (PWM) approach enabling the undistorted operation of the rectifier in all feasible operating conditions is thus proposed. Moreover, novel analytical expressions defining the maximum rectifier mid-point current capability and the minimum peak-to-peak DC-link mid-point charge ripple as functions of both modulation index and power factor angle are derived, the latter enabling a straightforward sizing of the split DC-link capacitors. The theoretical analysis is verified on a 30kW, 20kHz T-type rectifier prototype, designed for electric vehicle ultra-fast battery charging. The input phase current distortion, the maximum mid-point current capability and the minimum mid-point charge ripple are experimentally assessed across all rectifier operating points, showing excellent performance and accurate agreement with the analytical predictions.

“…The three-phase three-level Vienna-type rectifier has become increasingly popular for many advantages [1][2][3][4][5][6][7][8][9][10][11][12]. It offers the merits in terms of low-cost, high-power density, low grid side current total harmonic distortion (THD) and high-power factor [5,6].In addition, it is well known that it only needs three active switching components to produce three-level voltage [8,9]. Therefore, the cost-effective topology has been one of the most preferred choices considering both power density and cost, notably in aircraft application, telecommunication system, electrical drive power supplies and so on [10,12].…”

This study proposes an improved direct power control (DPC) strategy based on sliding mode control (SMC) with dual closed loop for the Vienna-type rectifier to improve transient response during both start-up and load step-change periods and to guarantee stability in steady state. The inner power closed-loop utilises SMC-DPC controller to directly regulate the required rectifier's control voltage without transforming to synchronous rotating coordinate reference frame or tracking phase angle of the grid voltage, which simplifies the control system. In addition, the outer loop employs a novel sliding mode controller to improve the dynamic performance of the dc output voltage and the instantaneous power. Finally, the dynamic and steady-state performances of the grid current, dc output voltage, active/reactive power are experimentally investigated and compared with the conventional proportional-integral-DPC scheme, both the simulation and the experimental results demonstrated the dynamic performance and stability of the proposed control scheme.

The impending global energy crisis has opened up new opportunities for the automotive industry to meet the everincreasing demand for cleaner and fuel-efficient vehicles. This has necessitated the development of drivetrains that are either fully or partially electrified in the form of electric and plug-in hybrid electric vehicles (EVs and HEVs), respectively, which are collectively addressed as plug-in EVs (PEVs). PEVs in general are equipped with larger on-board storage and power electronics for charging or discharging the battery, in comparison with HEVs. The extent to which PEVs are adopted significantly depends on the nature of the charging solution utilized. In this paper, a comprehensive topological survey of the currently available PEV charging solutions is presented. PEV chargers based on the nature of charging (conductive or inductive), stages of conversion (integrated single stage or two stages), power level (level 1, 2, or 3), and type of semiconductor devices utilized (silicon, silicon carbide, or gallium nitride) are thoroughly reviewed in this paper.Index Terms-Electric vehicles (EVs), inductive charging, plug-in hybrid electric vehicles (PHEVs), power electronics, wide-bandgap semiconductor devices.
