A Novel Algorithm for Precise Voltage Flicker Calculation by Using Instantaneous Voltage Vector
IEEE Transactions on Power Delivery, 2006A novel approach has been presented in this paper to calculate voltage flicker components precisely by using instantaneous voltage vectors. After the voltage waveform of a phase is recorded, the smart discrete Fourier transform can be used to obtain the system frequency and magnitude.

A Multidimensional Space Vector PWM Algorithm using Branch Space Voltage Vector
IEEE Transactions on Power Electronics, 2016Typical 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.

Voltage Vector Analysis for Corona Location in Transformers
IEEE Transactions on Power Apparatus and Systems, 1971Location of corona or "partial discharges" in transformers can be an extremely difficult, costly and time-consuming process, especially if disassembly is required. The present state-of-the-art is such that a variety of sonic and electrical corona location techniques are employed, none of which is completely adequate, but with experience and patience ...

Space vector modulation of a seven-phase voltage source inverter
International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2006. SPEEDAM 2006., 2006A generalized multi-phase space vector theory is considered for developing the space vector modulation of a seven-phase voltage source inverter. The modulation is based on the control of the voltage vector in the first d-q plane, imposing to be zero the voltage vectors in both the second and the third d-q planes. The proposed switching pattern includes

Space Vector Modulation of a Nine-Phase Voltage Source Inverter
2007 IEEE International Symposium on Industrial Electronics, 2007A generalized multi-phase space vector theory is considered for developing the space vector modulation of a nine-phase voltage source inverter (VSI). The space vector modulation (SVM) is based on the control of the voltage vector in the first d-q plane, imposing to be zero the voltage vectors in second, third, and fourth d-q planes, as in the relevant ...

High Voltage Solid State Switched Vector Inversion Generator
2007 IEEE Pulsed Power Plasma Science Conference, 2007A Vector Inversion Generator, VIG, consists of two parallel plate transmission lines, sharing a common conductor that have been wound on a mandrel. These units can be made highly efficient and are capable of developing high transient voltages in a time that is determined by the two way transit time for an electromagnetic wave to propagate up the ...

Support vector machines for an efficient representation of voltage band constraints
2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies, 2011Future Smart Grids emphasize the (at least) partial coordination of a large number of stochastic consumers and producers to balance consumption and generation of electrical energy. However, this coordinated and often time-synchronous activation and deactivation of demand and supply may result in the violation of the grid's feasibility constraints ...

On-chip voltage-droop prediction using support-vector machines
2014 IEEE 32nd VLSI Test Symposium (VTS), 2014Voltage droop is a major reliability concern in nano-scale VLSI designs. Undesirable voltage droop occurs when logic gates in the circuit draw high switching current from the on-chip power supply network, and this problem is exacerbated at high clock frequencies and smaller technology nodes.
