“…During charging, the voltage level of the grid side stator winding is adjusted by controlling the motor flux (the direct component of the current). The voltage angle is adjusted by speed control of the motor by means of the quadrature component of current [19]. The simulated model of the integrated charger for traction and charging mode is designed by using Matlab/Simulink.…”

“…The rotor speed error (the difference between the reference speed and true speed) is added to the controller by the means of a proportional controller to reduce these oscillations [2], [18]. By changing the set point of the direct and quadrature component of the current, the bidirectional flow of real and reactive power within the system can be controlled [19]. …”

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.

“…If we try to maximize the reluctance torque, we can call the machine an RTPM machine, where the PM torque, however, remains as the main torque [21]. As the i d component in the RTPMs during motoring is negative, there will be an extra positive torque created by the latter components in (3).…”

Hybrid and full electric technologies are fast emerging in vehicles and mobile working machines, where electric machines and internal combustion engines are used together to power the systems. Permanent magnet (PM) technology plays an important role here despite the high magnet prices. This paper theoretically and empirically studies the design principles of PM synchronous machines (PMSMs) for hybrid applications, where a high starting torque and a wide field weakening range are needed. Several embedded-magnet PMSM magnetic circuit topologies are considered as possible candidates. A 10-kW PMSM prototype was built and tested. Experimental results verify the theoretical considerations well.

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.
