AbstractMultiphase variable-speed drives and generation systems (systems with more than three phases) have become one of the mainstream research areas during the last decade. The main driving forces are the specific applications, predominantly related to the green agenda, such as electric and hybrid electric vehicles, locomotive traction, ship propulsion, 'more-electric' aircraft, remote offshore wind farms for electric energy generation, and general high-power industrial applications. As a result, produced body of significant work is substantial, making it impossible to review all the major developments in a single paper. This paper therefore surveys the recent progress in two specific areas associated with multiphase systems, namely power electronic supply control and innovative ways of using the additional degrees of freedom in multiphase machines for various nontraditional purposes.Index TermsMultiphase variable-speed drives, ac-ac converters, inverters, PWM, multiphase power electronics, integrated on-board battery chargers.

“…One of inherent benefits is harmonic current, and they are usually injected into stator winding to improve torque density [9][10][11]. Most of literature focuses on five-phase motor [12][13], and the torque density has been improved by third harmonic current for induction motor (IM), permanent motor and synchronous reluctance motor.…”

Φ Abstract-This paper investigates a novel harmonic current injection method to optimize air-gap and yoke flux density distribution for multiphase motor simultaneously. The effect of harmonic currents on air-gap flux density and yoke flux density is analyzed as a whole. The proposed method fully makes use of multiple control freedoms, and the optimal coefficients for corresponding harmonic current are derived. Maintaining the same stator current density, a nine-phase induction motor improves torque density about 6.6% with the proposed method. A three-phase induction motor is designed to verify the effectiveness of multiphase motor with concentrated fullpitched winding. Furthermore, the torque density and efficiency for two motors are compared under various load condition. Finally, a multiphase variable speed drive system is constructed and the proposed method is validated by experiments.

“…For instance, sensorless rotor-field oriented control (RFOC) [31], sensored RFOC with fuzzy logic [30] and direct torque control [32] are reported. Open-end winding topologies are a modern topic considered mainly for induction machine-based drive systems [33][34][35][36]. A series open winding connection of a PMSM stator was suggested earlier to interface a generator-engine set to an existing renewable energy source without an additional VSC [37].…”

This study proposes a new architecture of flywheel energy storage system (FESS) which can be implemented at generating unit (GU) level (e.g. wind turbine) or scaled up for application in grid-side converter (GSC) stations of a multiterminal direct current (MTDC) system. The proposed architecture suppresses DC voltage leaps under grid faults, and performs power levelling duty at grid connection points. When implemented at GU level, the proposed FESS features a doubly-fed induction machine (DFIM) -the flywheel machine -where its six stator winding terminals are connected in series between the grid and the GSC. The flywheel converter is of partial power rating, and is connected to the DFIM rotor. When employed at an MTDC GSC station, several submodules are connected to build an FESS station. The study proposes the control concept and the general topology of the FESS station. The performance parameters of the system are tested under normal and abnormal operating conditions. Results and analyses indicate smooth dynamic operation, the economic advantage and the improved fault ride-through capability because of the proposed system.
