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...
متن کاملMultilevel Inverters Based On Space Vector Pulse Width Modulation Technique
In this paper, a simplified space–vector pulse width modulation technique for multilevel inverters is proposed. This method is based on the simplification of the space–vector diagram of a five level inverter into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Hence, the algorithm of five level space-vector pu...
متن کاملDesign of Three Phase Inverter Using Space Vector Pulse Width Modulation Technique (SVPWM)
A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter. The different methods for PWM generation can be broadly classified into Triangle comparison based PWM ...
متن کاملPerformance of Sinusoidal Pulse Width Modulation based Three Phase Inverter
In this paper a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. . The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. The fundamental component of the three-phase line-to-line voltage is increased by about 15 percent above than that of the conventional sine-wave inverter. The sinusoidal PWM switching scheme allo...
متن کاملPulse width modulation managing application
This article describes software application, that generates voltage pulses. The input commands are Musical Instruments digital interface messages. As already mentioned the name of it is the interface that is used primarily to control musical instruments through the computer. But this software is mentioned for all electridcal device without any communication protocol. E.g. DMX protocol and other...
