“…2, the 3H-Bridge converter uses a machine without neutral point. The advantage of this architecture is to allow the application of the full DC link voltage to each PMSM stator winding [10]- [12]- [26]. However, with this specific architecture, the zero-sequence current is not structurally rejected, unlike the classical solution with a star neutral point topology [27].…”

Abstract-This paper deals with a synthesis of Space Vector PWM control methods applied for a H-bridge inverter feeding a 3-phase Permanent Magnet Synchronous Machine in Electric Vehicle application. First, a short survey of existing power converter architectures, especially those adapted to degraded operating modes, is presented. Standard SVPWM control methods are compared with three innovative ones using EV-drive specifications in the normal operating mode. Then, a rigorous analysis of the margins left in the control strategy is presented for a semiconductor switch failure to fulfill degraded operating modes. Finally, both classic and innovative strategies are implemented in numerical simulation; their results are analyzed and discussed.

As for any embedded transportation system, these power converters are subject to severe constraints especially regarding compactness and vehicle integration. More specifically electric vehicles (EVs) require a high degree of availability (continuity of service). In particular the constraining automotive environment is characterized by severe traction-braking cycles which induce power and thermal cycling during running phases of the vehicle [1]- [2]. Indeed, thermo-mechanical stresses have a significant impact on the lifetime power switches [3]. Consequently, there is a degradation of the semiconductor devices, which finally forces them into a failed state: short-circuit (SC) or open-circuit (OC) [2]. Such failures occurring on single power switches can affect the function of power converters and spread through the traction chain elements. It is then necessary to first isolate the fault, confine it and lastly reconfigure the control algorithms to operate in the presence of the fault. Obviously, the topology of the power converters or the power chain must be adapted to allow operation in degraded mode:-by associating a fourth additional half bridge in a three-phase inverter topology connected to the neutral point of the electric motor [4]. IFSTTAR/COSYS/LTN-Laboratoire des Technologies Nouvelles 2 LGEP-Laboratoire de Génie Electrique de Paris-by using multilevel inverters topologies used in a high power traction drive [5].-by redistributing the control efforts in a four-wheel independently driven electric vehicles [6]… Furthermore, faults may also happen on sensors and can be taken into account by active fault-tolerant control systems. For example in [7]-[8], authors consider a high-performance induction-motor drive for an EV or a hybrid one (HEV). The proposed systems detect a sensor loss or a sensor recovery and dynamically change its strategies to sustain the best control performances.Besides, faults may also occur in the electrical machine and can be considered using fa...

“…In addition, there is no neutral point for the machine connected with the converter with three Hbridges, thus the full DC-link voltage to each PMSM stator winding can be applied [83,84], while the zero-sequence current cannot be structurally rejected. The specific SVPWM method which is most suitable for EV requirement was selected by combining all the following advantages: switching loss minimization, balanced switching rate between the three H-bridges, insensitivity to duty cycle, maximized drive performance, and reduction of the zero-sequence current ripple [82].…”

“…On-board bidirectional chargers can be further divided into two main types of structures: reused (or integrated) structures and independent structures. In the reused structure, the EV motor's inverter is used as the full-bridge circuit of the grid-tied inverter; the EV motor's windings as the input inductances of the grid-tied inverter; and the EV motor itself as a line-frequency transformer for galvanic isolation [40][41][42][43][44][45][46][47][48]. By using the existing system in the EV, the reused topologies incur lower costs.…”

Abstract:In vehicle-to-grid (V2G) systems, electric vehicles interact with the grid as distributed energy storage systems that offer many potential benefits. As an energy interface between a vehicle and the grid, the bidirectional converter plays a crucial role in their interaction. Its reliability, safety, cost, efficiency, weight, size, harmonics, and other factors are of essential importance for V2G realization, especially for on-board operations. Beyond the common existing topologies for bidirectional chargers, this paper introduces a novel high-power-factor bidirectional single-stage full-bridge (BSS-FBC) topology, which offers advantages in power density, size, weight, cost, efficiency, power quality, dynamic characteristic, reliability, and complexity. Its operational principles and control strategies are presented. Harmonic analysis on the basis of double-Fourier integral is performed with detailed comparison of line current harmonic characteristics between the BSS-FBC topology and unipolar/bipolar controlled single-phase pulse width modulation (PWM) converters. A dynamic model of the topology is derived, its dynamic behavior analyzed, and its compensator design method developed. Simulation and experimental results are employed to verify the design and analysis. Design considerations for the key parameters are discussed. A 3.3 kW prototype is developed for this topology and validated in its vehicle applications. The results demonstrate clearly the benefits and advantages of the new topology.
