The employments of Multilevel DC Link Inverters offer dependable points of interest attributable to the expansion in the highest levels at the yield output voltage and are broadly acknowledged for industrial applications. The execution of these bores on high when contrasted with the routine conventional two-level inverters because of their drawbacks. Be that as it may, the expanded number of devices,...
Reactive power is one of the most significant ways that electricity is lost when it travels along power lines, resulting in the use of larger equipment on the distribution system. There is also a corresponding increase in the amount of greenhouse gases that get released into the atmosphere. The solution to these problems lies in power factor correction (PFC) where in less reactive power will be drawn...
Hysteresis pulse width modulation has different application because of its unmatched dynamic response and wide command tracking bandwidth. The various hysteresis modulation schemes are available in literature for multilevel inverter. The techniques are desired and compare the reference signal to obtain the adequate switching frequency, excellent dynamic response and high accuracy in steady state operation...
Voltage source inverter (VSI) fed induction motors are widely used in variable speed applications. Space Vector Pulse Width Modulation (SVPWM) has become the successful techniques to construct three phase sine wave Voltage Source Inverter (VSI) parallel to control three-phase induction motor using v/f control. Because of the low maintenance and robustness induction motors have many applications in...
T A voltage source inverter-fed induction motor produces a pulsating torque due the application of no sinusoidal voltages. Torque pulsation is strongly influenced by switching fashion employed. This paper presents the simplified hybrid pulse width modulating technique for the reduction of torque ripples in an induction motor. In conventional space vector pulse width modulating (CSVPWM) technique (0127–7210)...
Selective Harmonic Elimination technique is one of the control methods applied in Voltage Source Inverters to eliminate the harmonics. However, finding the solutions for the harmonic reduction is a difficult problem to be solved. This paper presents an efficient and reliable Evolutionary Algorithms based solution for Selective Harmonic Elimination (SHE) switching pattern to eliminate the lower order...
This paper presents an efficient and reliable evolutionary-programming-based algorithm for specific harmonic elimination (SHE) switching pattern. This method eliminates the considerable amount of lower order line current harmonics in pulse width modulation (PWM) inverter. Determination of pulse pattern for the elimination of some lower order harmonics of a PWM inverter necessitates solving a system...
