“…In order to be able to cancel the torque oscillations, recalling (6), it would suffice to cancel out current i q . Using the definition introduced in (4) one could write By using the two degrees of freedom aforementioned in (9), and forcing i q = 0 in (11), the expression for the current i b is given by…”

“…The propulsion inverter can be easily adapted for the charging process, and the motor windings could be employed as inductive filters. Some authors propose to use additional rectifiers for the AC/DC conversion from the grid, then the machine windings as inductors for a DC/DC converter [9]- [11]. The main draw- VOLUME 4, 2016 back is the need of additional components that will translate into an increment of the cost, losses, volume and weight.…”

Although there is a growing interest in developing fast charging methods to enhance the Electric Vehicles' appeal, the main energy supply is still the single-phase outlet. While single-phase charging may be simpler than three-phase, there are challenges in the integration of the propulsion and charging systems without adding inductive grid filters. Such integration would bring benefits like the simplification and reduction of components, costs, volume or weight. This can be achieved by using the windings of the propulsion machine as grid filters, but the use of the electric motor as a grid inductive filter leads to the generation of pulsating torque during the charging state. This translates into vibration, noise and eventually, damage to the motor and other components of the system. In this work, the authors propose a control strategy that considerably reduces the peaks of pulsating torque generated in any rotor position while using the machine wingdings as filter. Simulation tests have been carried out to validate the control strategy, taking into account the system efficiency. Finally, experiments are conducted to prove that the reduction of the torque pulsation is achieved.INDEX TERMS Integrated charger, Electric Vehicles (EV), permanent magnet synchronous motor (PMSM), battery charger

“…The operation of this structure has already been practically confirmed for two different modes of operations: Different Frequencies (DF) mode, which can be used to drive two threephase ac motors independently, and Common Frequencies (CF) mode, which can be used to control the operation of a six-phase motor [3]- [7]. Various carrier-based (CB), space vector PWM and model predictive control techniques have been proposed to achieve superior performance of the NSI for both DF and CF modes [1]- [4], [8]- [12].…”

“…The increased emphasis on environmental protection has accelerated the development of greener modes of electrified transportation, and has led to the rise of renewable energy industries. The advantages of multiphase machines attract researchers to utilize them in electric and hybrid electric vehicles (EVs), e.g., on-board battery chargers for EVs with three-phase machines [14], five-phase machines [15], six-phase machines [16,17], and ninephase machines [18]. Besides, they are also considered preferable solutions for wind power generation systems due to the power sharing capability [19], modularity [20], additional degrees of freedom [21], and fault-tolerant capability [22,23] provided by their multiphase topologies.…”

Multiphase electrical machines are advantageous for many industrial applications that require a high power rating, smooth torque, power/torque sharing capability, and fault-tolerant capability, compared with conventional single three-phase electrical machines. Consequently, a significant number of studies of multiphase machines has been published in recent years. This paper presents an overview of the recent advances in multiphase permanent magnet synchronous machines (PMSMs) and drive control techniques, with a focus on dual-three-phase PMSMs. It includes an extensive overview of the machine topologies, as well as their modelling methods, pulse-width-modulation techniques, field-oriented control, direct torque control, model predictive control, sensorless control, and fault-tolerant control, together with the newest control strategies for suppressing current harmonics and torque ripples, as well as carrier phase shift techniques, all with worked examples.
