Active filter controlled by differentiation of current vector
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003In this paper, a new control technique is proposed for the active filter using the current source converter. The control circuit of the proposed system is very simple, because the references of compensation currents aren't necessary. The compensation of line current with a filter circuit can be automatically obtained by PWM control based on the ...

An Integrated Vector Control Strategy for BLDC Current
2019 IEEE 3rd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2019To improve the flux-weakening capability of a brushless DC motor (BLDC) with trapezoidal wave, here is a 120° conduction square wave control stratgey. In this paper, a novel current integrated vector control strategy is proposed based on stator current prime vector.

2005 International Conference on Electrical Machines and Systems, 2005
A universal current vector controller for vector-controlled induction motor (IM) drives, based on control of motional electromotive force (MEMF), is presented. It is demonstrated that the rotor field orientation decouples not only flux and torque but also transformer electromotive force (TEMF) and MEMF in rotor.

Current Regulation Strategies for Vector-Controlled Induction Motor Drives
IEEE Transactions on Industrial Electronics, 2012Dynamically accurate torque control is an essential prerequisite for higher performance motor drive systems. For ac induction motors (IMs), the two most established strategies are direct torque control (DTC) and vector or field orientated control. DTC directly switches the inverter to regulate torque without requiring explicit stator current regulation.

IM Torque Control Schemes Based on Stator Current Vector
IEEE Transactions on Industrial Electronics, 2014This paper proposes an induction machine torque control derived from the model in the stator current vector reference frame. The required torque is produced by simultaneously manipulating the magnitude and the rotation speed of the stator current vector, thus forcing the rotor flux linkage vector to change implicitly in such a way that overall ...

Research of Hysteresis PWM Rectifier Based on the Current Vector Control
2008 IEEE Pacific-Asia Workshop on Computational Intelligence and Industrial Application, 2008According to high power factor and the actual project needs which are requirements of three-phase rectifier control as known, the research of three-phase PWM rectifier is based on the current vector control. The system still adopts hysteresis current control strategy.

Multilevel current source converter (MCSC) is an effective way to increase the power rating of conventional current source-fed motor drive, especially its current rating. However, there are still several challenges existing in this kind of configuration, which mainly focus on its space vector modulation (SVM) technique and the inherent DC current ...
