Active filter controlled by differentiation of current vector

Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003
In 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 improved space-vector-based hysteresis current controller

IEEE Transactions on Industrial Electronics, 1998
In this paper, an improved space-vector-based hysteresis current controller (SVBHCC) is proposed. The controller determines a set of space vectors from a region detector and applies a space voltage vector selected according to the main HCC. A set of space vectors including the zero voltage vector to reduce the number of switchings is determined from ...

Inverter nonlinearities and discrete-time vector current control

IEEE Transactions on Industry Applications, 1994
The authors study all-digital discrete-time vector current control loops containing a voltage-fed inverter in series with a permanent magnet synchronous motor. Normal operation of the typical pulse width modulating voltage fed inverter introduces nonlinear distortion into the voltage and the current waveforms of the motor. The authors consider both the

Current Controller for Autocommissioned Vector-Controlled Induction Motor Drives

Electric Machines & Power Systems, 2000
A current controller composed of a current regulator associated to a parameter adaptation scheme is proposed. The current regulator considers the inherent coupled structure of the induction machine. The adaptive block is coupled to this regulator in order to carry out a high performance current control with low sensitivity to parameter variations.

Current control in overmodulation range for space vector modulation based vector controlled induction motor drives

2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002
Overmodulation enhances the power utilization of the installed capacity of a voltage source inverter. A space vector strategy is used for constant switching frequency inverters. In order to achieve the overmodulation a modified reference signal with nonuniform angular velocity is generated using a preprocessor.

Control of DFIG Wind Turbine With Direct-Current Vector Control Configuration

IEEE Transactions on Sustainable Energy, 2012
The doubly-fed induction generator (DFIG) wind turbine is a variable speed wind turbine widely used in the modern wind power industry. At present, commercial DFIG wind turbines primarily make use of the technology that was developed a decade ago. But, it is found in this paper that there is a limitation in the conventional vector control technique ...
