CORDIC Implementation of Space Vector Modulation

2008 IEEE Industry Applications Society Annual Meeting, 2008
Space vector modulation (SVM) is commonly used in motor drives. In order to reduce the calculation time in SVM a coordinate rotation digital computer (CORDIC) algorithm is used to generate trigonometric functions. The algorithm is implemented using a microcontroller.

Comparison of vector sigma-delta modulation and space-vector PWM

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
The paper introduces certain modifications to the basic idea of vector sigma-delta modulation (VSDM), aimed to eliminate the polarity reversals in the line-line voltages, and to reduce the inverter switching losses. The performance of this modified VSDM is then compared with the space-vector PWM (SVPWM).

Vector-based reference location estimating for space vector modulation technique

Electric Power Systems Research, 2012
Abstract Space vector modulation (SVM) has become a popular pulse width modulation technique (PWM) for multilevel inverters. In SVM technique, the determination of the angular position of the reference voltage vector is very important to generate the required output voltage by the inverter.

Space vector modulator for forced commutated cycloconverters

Conference Record of the IEEE Industry Applications Society Annual Meeting, 2003
A pulse-width modulation (PWM) control technique for forced commutated cycloconverters is presented. The technique is based on the space vector representation of the voltages in the complex plane. It is shown that with the allowable switching combinations, six output voltage space vectors with varying amplitudes can be obtained, in addition to the zero

Space Vectors Modulation for Nine-Switch Converters

IEEE Transactions on Power Electronics, 2010
Recently, nine-switch inverter and nine-switch-z-source inverter have been proposed as dual output inverters. In this paper, the space vector modulation (SVM) of nine-switch inverter and nine-switch-z-source inverter is proposed. The proposed method increases the sum of modulation indices up to 15% in contrast with the conventional, scheme in which the

FPGA-based universal multilevel space vector modulator

31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005
This paper presents a new circuit design of multilevel space vector modulation (SVM) strategy. This strategy is based on the decomposition of the reference voltage, and it is utilized at any number of levels. The proposed algorithm has been realized using field programmable gate array (FPGA) technology.
