Multi-vector SVM: a new approach to space vector modulation control for six-phase induction machines
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005 In this paper, a new space vector modulation (SVM) technique for six-phase induction machines (SPIM) is presented. The machine has two three phase stator windings spatially shifted by 60 electrical degrees and connected to a single neutral. The neutral point may be connected to the source or not.

Industrial Electronics, 2002. ISIE 2002. Proceedings of the 2002 IEEE International Symposium on, 2002 This paper presents digital signal processor (DSP) based direct torque control scheme using space vector modulation (DTC-SVM) for permanent magnet synchronous motor (PMSM) drives. The analysis of PMSM shows that the increase of electromagnetic torque is proportional to the increase of the angle between the stator and rotor flux linkages and therefore ...

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018 Modular multilevel converters (MMC) can be used in many applications such as medium voltage multimegawatt drives and HVDC power transmission. Modulation strategy plays an important role for the good performance of MMC. In this paper, a submodule (SM) regrouping method of MMC is presented and based on this, a sampling time staggered space vector pulse ...

Flux Control with Space Vector Modulation (FC-SVM)
EUROCON 2007 - The International Conference on "Computer as a Tool", 2007 In this paper a simple method for electric motor control is presented -Flux Control with Space Vector Modulation (FC-SVM). The FC-SVM can be applied both for induction and synchronous machine (similar to Direct Torque Control with Space Vector Modulation DTC-SVM). This method is based on error between reference and actual stator flux vector modulation.

2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), 2020 This paper presents a model-based implementation of modified space vector modulation (SVM) for a three-level three-phase active neutral-point clamped (ANPC) rectifier. To optimize and reduce the number of high frequency active switches, this paper uses a hybrid modulation technique in which only two switches out of 6 active switches are switching at ...

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011 This work presents a new Direct Torque and Flux Control (DTFC) method for induction motors using a novel form of Model Predictive Control (MPC). This MPC strategy is novel from the point of view of the power supply (a three phase inverter) since, instead of using a single voltage vector as the control action during a complete sampling period of the ...

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016 A current soft-commutation Space Vector Modulation (SVM) scheme for three-phase current source converter (CSC) is proposed in this paper. With the presented SVM, the incoming switch has a positive collector-to-emitter voltage while the outgoing switch has a negative collector-to-emitter voltage during current commutations.

2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING, 2011 Performance evaluation of two levels unidirectional PWM rectifiers employing space vector modulation will be discussed in this proposed work. A methodology for the use of this modulation is proposed and applied in different group of rectifier. For each group of rectifier the converter switching techniques are analyzed to determine switch control ...

2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC), 2019 Direct torque control (DTC) scheme is one of the most appropriate methods to control of AC machines. This method has positive features such as fast response, simple structure and low dependence on motor parameters. However, the main problems in classic DTC method are variation of switching frequency and high ripple of flux and torque.
