Fast Space Vector Algorithm of Pulse Width Modulation Rectifier

2007 IEEE International Conference on Control and Automation, 2007
A novel space-vector sector judgment method for the three-phase PWM rectifier is presented. The sector of expected voltage vector can be judged according to the component polarity of expected voltage vector in the three-phase static coordinates. Compared with the traditional space-vector judgment method, no needs calculating of sinusoidal and arctan ...

Based on space-vector pulse-width modulated reversible rectifier

ICEMS'2001. Proceedings of the Fifth International Conference on Electrical Machines and Systems (IEEE Cat. No.01EX501), 2002
This paper presents a simple control scheme of three-phase rectifier based on space-vector pulse-width modulation (SVPWM). The realization of the regenerating operation is illustrated in detail and the predicted current control is introduced for avoiding the phase shift between the input voltage and the input current.

Space vector pulse width modulation control of induction motor

IET-UK International Conference on Information and Communication Technology in Electrical Sciences (ICTES 2007), 2007
Variable voltage and frequency supply to AC drives is invariably obtained from a three-phase voltage source inverter. A number of pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply. The most widely used PWM schemes for three-phase voltage source inverters are carrier-based sinusoidal PWM and space vector PWM ...

Space Vector Pulse Width Modulation for Multilevel Inverter - A Survey

2018 4th International Conference for Convergence in Technology (I2CT), 2018
In this paper, a survey of different space vector pulse width modulation (SVPWM) techniques for multilevel inverter (MLIs) are presented. The performance of any MLIs depends upon the selection of modulation technique. Compared to many PWM techniques, SVPWM is the preferred technique due to lower switching losses, high DC bus utilization, lower harmonic

Space Vector Pulse Width Modulation for Three-Level NPC-VSI

IEEE Latin America Transactions, 2013
This work addresses the design and experimental validation of a three-level Neutral-Point Clamped (NPC) inverter. A Space-Vector Modulation (SVM) algorithm which simplifies the space-vector diagram of a three-level inverter so that it can be used with a two-level inverter is developed. The dwell times are calculated on the simplification process in the
