Modified Space Vector Pulse Width Modulation for Z-Source Inverters

This paper presents a Modified control method for Space Vector Modulated (SVM) Z Source inverters. Proposed algorithm provides a modified voltage vector with single stage controller having one degree of freedom wherein traditional controllers have two degrees of freedom. Through this method of control, the full utilization of the dc link input voltage and keeping the lowest voltage stress acros...

The Vector Control of Three-Phase Salient Pole Synchronous Machines Supplied by Pulse-Width- Modulated Voltage Source Inverters

In this paper, computer simulation of a three-phase synchronous motor drive is described. This drive/system is supplied with a new type of pulse-width modulated voltage source inverter (PWM VSI) whose amplitude of the first harmonic, compared to a conventional sinusoidal PWM VSI, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...

Superfast multifrequency phase-shifting technique with optimal pulse width modulation.

The technique of generating sinusoidal fringe patterns by defocusing squared binary structured ones has numerous merits for high-speed three-dimensional (3D) shape measurement. However, it is challenging for this method to realize a multifrequency phase-shifting (MFPS) algorithm because it is difficult to simultaneously generate high-quality sinusoidal fringe patterns with different periods. Th...

FPGA Implementation Of Hybrid Pulse Width Modulation Strategies For Three Level Inverters

This paper sprays five hybrid pulse width modulation strategies for three level inverters in FPGA platform. The proposed hybrid-modulation strategy is an amalgamation of fundamental-frequency modulation and any carrier based pulse width modulation (SPWM) invoking the performance of the well-known carrier based PWM modulations. The main philosophy of this modulation is the reduction of switching...
