A three-phase PWM rectifier with active filtering function

Proceedings. International Conference on Power System Technology, 2003
This paper presents a multi-function converter (MFC) as a viable solution to improve the power quality. The PWM rectifier (PWMR) operates as a rectifier to supply DC power to its linear or pulsating load and at the same time, operates as a shunt active power filter (APF) to improve the power-factor and to compensate harmonic and unbalanced currents ...

Discrete time control design of three phase PWM rectifiers

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
A high bandwidth discrete time controller for three phase PWM rectifiers which optimizes the dc-link stiffness with respect to load variations is introduced. Based on one derived discrete time model of the PWM rectifier the control implementation and design is illustrated.

Power control of three-phase PWM rectifier for microturbine

2010 2nd International Conference on Advanced Computer Control, 2010
Microturbine generator system is one of the most promising distributed generation systems because it is small, efficient and mobile. When it is running, the high-frequency alternating current of permanent magnet synchronous generator generating must be rectified and inverted into 50Hz AC to meet the user requirements.

SVM-based hysteresis current controllerfor three-phase PWM rectifier

IEE Proceedings - Electric Power Applications, 1999
A space vector modulation (SVM) based hysteresis current controller (HCC) for the pulse width modulated rectifier is proposed. The proposed technique utilises all the advantages of the HCC and SVM techniques. The controller determines a set of space vectors from a region detector and applies a space vector, selected according to the HCC. A set of space

Direct Power Control Strategy of Three-phase PWM Rectifier

Journal of Information and Computational Science, 2013
For traditional Direct Power Control (DPC), the switching frequency is not fixed and the characteristics in steady state are not well. In order to solve these problems, a proposed DPC strategy based on virtual flux is designed. Firstly, the mathematical model of three-phase PWM rectifier is presented.

A three-phase PWM rectifier with reactive power compensation function

2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
This paper presents a new type of three-phase PWM rectifier with reactive power compensation function. The rectifier compensates reactive power based on its rated capacity. Under light and medium load, the rectifier has enough capacity to fulfill both reactive power compensation and PWM rectifier tasks.

Constrained model predictive control for a three-phase PWM rectifier

2017 Chinese Automation Congress (CAC), 2017
In this paper, constrained model predictive control (MPC) based on parallel neural network optimization is proposed to apply to pulse width modulation (PWM) rectifier and improve power quality. An decoupled model of three-phase rectifier in abc coordinates is built. Then, the constrained MPC method is proposed.

Conducted EMI Analysis of a Three-Phase PWM Rectifier

2010
Because of the strict electromagnetic interference (EMI) regulation, noises generated from high switching frequency converters need to be analyzed and suppressed by some methods. EMI noises in power converters are generally frequency related. This paper investigates the mechanisms of conducted EMI emissions associated with the typical three phases PWM ...
