“…Electric vehicles (EVs) are increasingly a reality of our days; however, the widespread introduction of EVs in the market has been constrained by several technical issues, limiting their performance and increasing their cost. Thus, the introduction of EVs brings new opportunities, namely their integration into the power grid as a stabilizing element, and also contributes to improving energy efficiency and cost reduction [1][2][3].…”

An electric vehicle (EV) usually has two main power converters, namely one for the motor drive system and another for the battery-charging system. Considering the similarities between both converters, a new unified power converter for motor drive and battery charging of EVs is propounded in this paper. By using a single unified power converter, the cost, volume, and weight of the power electronics are reduced, thus also making possible a reduction in the final price of the EV. Moreover, the proposed unified power converter has the capability of bidirectional power flow. During operation in traction mode, the unified power converter controls motor driving and regenerative braking. Additionally, during operation in battery-charging mode, with the EV plugged into the electrical power grid, the unified power converter controls the power flow for slow or fast battery charging (grid-to-vehicle (G2V) mode), or for discharging of the batteries (vehicle-to-grid (V2G) mode). Specifically, this paper presents computer simulations and experimental validations for operation in both motor-driving and slow battery-charging mode (in G2V and V2G modes). It is demonstrated that the field-oriented control used in the traction system presents good performance for different values of mechanical load and that the battery-charging system operates with high levels of power quality, both in G2V and in V2G mode.

“…Along with the solid state switches of the drive meant for feeding power to the traction machine, the AC side inductors can help in realizing a boost AC-DC converter to improve the power factor while charging. Most of the existing literatures on IC focus on various circuit topologies [1]- [5] and charger performances [5], [6]. This paper rather aims to explore the happenings inside a PMSM when AC current is flowing through its armature windings.…”

During integrated charging (IC) operation employing permanent magnet machines, the magnetic field produced by the sinusoidal AC current passing through the stator windings, a) affects the effective winding inductance used in the charger circuit as a function of different stator winding combinations; and b) produces oscillating torque of varying magnitudes as a function of rotor position. Understanding the above challenges, this paper exclusively investigates the electromagnetic effects inside a surface-mounted permanent magnet synchronous machine (SPMSM) when it is used for IC operation in electric vehicles. Variation of oscillating electromagnetic torque magnitude as a function of rotor angle is investigated through finite element analysis and recommendations are provided to determine the lowest torque position favorable for IC operation. Thereafter, numerical investigations are conducted for five different stator winding combinations to analyze the issue of varying effective inductance as a result of magnetic coupling in the motor. Furthermore, a mathematical model is developed to obtain these inductances in the five winding configurations. Finally, the numerical investigations are validated by performing experimentations on a 21 hp SPMSM.
