A Multidimensional Space Vector PWM Algorithm using Branch Space Voltage Vector

IEEE Transactions on Power Electronics, 2016
Typical algorithms of multidimensional space-vector pulsewidth modulation (SVPWM) divide ( n –1) dimensional space into ( n –1)/2 subplanes with decoupling matrix or symmetrical component approach. However, the determination of effective sectors and appropriate space voltage vectors takes a heavy computing burden.

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).

A Simplified Space-Vector PWM Scheme for N-Level NPC Inverter Based on Two-Level Space-Vector PWM

2014 IEEE Vehicle Power and Propulsion Conference (VPPC), 2014
This paper proposes a general dwell-time equations for N-level inverter that are derived without the complex calculation. Contrary to the conventional method which has two dwell-time equations due to types, the proposed dwell-time equation is defined as one equation without the separated types. This method proceeds following step.

Interleaved PWM with discontinuous space-vector modulation

IEEE Transactions on Power Electronics, 1999
This paper describes the effect of interleaved discontinuous space-vector modulation (SVM) in paralleled three-phase systems using three-phase pulsewidth modulation (PWM) rectifiers as an example. At the discontinuous point of the SVM, the phase shift between the switching signals of the paralleled modules generates a zero-sequence excitation to the ...

Space vector PWM control of BLDC motor

2017 International Conference on Power and Embedded Drive Control (ICPEDC), 2017
A brushless dc motor is characterized by high efficiency with good life time. For a motor to have high performance, it requires accurate speed and to recover quickly from any disturbances, sensitive to motor parameter variations. Different speed controllers are widely used to operate the motor with proper reference speed.

An Approach for Design of Space Vector PWM Inverter

2019 4th International Conference on Electrical, Electronics, Communication, Computer Technologies and Optimization Techniques (ICEECCOT), 2019
One of the most preferred pulse width modulation (PWM) strategies today is space-vector modulation (SVPWM). This kind of scheme in voltage source inverter (VSI) drives offer improved bus voltage utilization and less commutation losses. Three-phase inverter voltage control by space-vector modulation includes switching between the two active and zero ...

FPGA-based space vector PWM with Artificial Neural Networks

2012 9th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2012
This article presents the improvement of a PWM technique, called Space Vector PWM (SVPWM), using an Artificial Neural Network (ANN) to minimize the mathematic complexity involved with the SVPWM. The latter is a pulse-width modulation technique that is wide implemented to control AC electric motors.

Space Vector PWM for PMSM simulation using Matlab Simulink

2010 IEEE Asia Pacific Conference on Circuits and Systems, 2010
Space Vector PWM (SVPWM) model is often built based on high-level functions and verified based on the output of the inverter or the model of the electrical motor with best possible accuracy. However, SVPWM implementation on digital hardware such as Field Programmable Gate Array (FPGA) and Application-specific Integrated Circuit (ASIC) is constrained by
