“…During charging, the inverter is synchronized with the grid voltage through stator windings of the electric machine. In order to keep synchronism, the gate pluses of switching devices of the bidirectional converter are synchronized with the grid voltage by using PWM technique [5], [8]. The stator windings act as an isolated three-phase transformer and the converter can control the dc voltage and current at the battery side [7].…”

“…It can be a suitable option for both onboard and off-board charger. Several different types of integrated chargers are proposed for vehicle application where the electric machine is used as inductor or isolated transformer and the vehicle remains standstill during charging [2], [5].For non-isolated integrated chargers, extensive protection and shielding are used [5]. However for isolated charger, a wound rotor induction machine is used as an isolated transformer which causes low system efficiency due to high magnetization current.…”

The operation and efficiency of HEV (hybrid electrical vehicle) greatly depends on its charging system. The HEV uses grid power to charge the battery. The traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger. Most charges are non isolated type having low charging power capacity. Therefore on board isolated high power charger is required for PHEV (plug in hybrid electrical vehicle) which may improve the charging efficiency of the battery. The size and price are important considerations for such integrated charger. In this paper, an integrated on board charger is proposed which provides high charging power and unity power factor operation. In the proposed design, asynchronous machine and bi directional converter are used so that the machine can act as motor during traction and isolated transformer during charging. The boost converter topology is used for the bidirectional converter which can be used as inverter during traction. The proper operation of integrated charger greatly depends on grid synchronization and controlling mechanism of converter and asynchronous machine. The Park transformation is used for mathematical electromechanical model of the asynchronous machine. A controller scheme is designed by using the concepts of conventional controlling scheme of IPM (induction permanent magnet) motor/generator set and decoupled current control method of boost converter. The whole system is simulated in Matlab/Simulink based model in order to verify the system operation of the proposed charger. The simulation results show good performance of the charger leading to machine speed stability and smooth grid synchronization.

“…Barnes and Pollock used SRM phase windings as a transformer during charging in [40], but without active PFC control. Haghbin et al [46] used an extra winding on one phase of the stator to have transformer operation for a single phase ac supply with a synchronous reluctance motor. In this case the stator will have unsymmetrical windings.…”

This paper reviews the current status and implementation of integrated charging methods for plug-in electric vehicles and hybrids. Battery charger systems are categorized into on-board and off-board types. An off-board charger can be designed for high charging rates and is less constrained by size and weight. Typical on-board chargers limit the high power because of weight, space, volume and cost constraints. Integration of the charging function into the electric drive system and electric motor has been developed to minimize battery charger costs, weight and volume. In an integrated charger, motor windings are used for the inductors. The motor drive inverter serves as a bidirectional ac-dc converter. Various integrated charger topologies are presented, compared, and evaluated based on cost, weight, suitability, configurations, and other factors.

“…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.
