Application of Bacterial Foraging Algorithm and Genetic Algorithm for Selective Voltage Harmonic Elimination in PWM Inverter
Pulse Width Modulation (PWM) techniques are increasingly employed for PWM inverter fed induction motor drive. Among various popular PWM methods used, Selective Harmonic Elimination PWM (SHEPWM) has been widely accepted for its better harmonic elimination capability. In addition, using SHEPWM, it is also possible to maintain better voltage regulation. Hence, in this paper, an attempt has been ma...
متن کاملSelective Harmonic Elimination in PWM Inverter Using Fire Fly and Fire Works Algorithm
This work considers new applications of Firefly and Fireworks algorithm for solving the selective harmonic elimination problem in inverter output waveforms. The higher order harmonics in the output of the inverter can be eliminated easily by using small passive filters. Lower order harmonic elimination requires selecting a pre-specified firing angle. That angle is one of the many solutions of a...
متن کاملHarmonic Elimination of Cascaded Multilevel Inverter for Medium-voltage Application
In this paper, a low-frequency squarewave inverter with a series-connected pulse width modulation (PWM) inverter is investigated for highpower applications. The series compensators produce only the desired harmonic voltages to make the net output voltage sinusoidal with small PWM switching harmonics only. An open-loop control strategy for the series compensator is proposed in this paper. This s...
متن کاملComparison of PWM Techniques and Selective Harmonic Elimination for 3-Level Inverter
In this paper comparison of Selective Harmonic Elimination (SHE) method with different Pulse Width Modulation (PWM) technique which are used as gate pulse for firing the IGBT‟s. Higher order harmonics are easily eliminated by selecting a proper tuned value filters but lower order harmonics such as 3rd, 5th, 7th, and 9th are not easily eliminated. This paper includes NewtonRapson method with ran...
متن کاملComparison of GA and PSO Algorithms in Cascaded Multilevel Inverter Using Selective Harmonic Elimination PWM Technique
The Selective Harmonic Elimination (SHE) technique is the fundamental switching frequency scheme which is used to eliminate specific order harmonics. In this paper, the elimination of low order harmonics in cascaded multilevel inverter with equal DC sources is proposed. The modulation strategy used here is SHEPWM in which non linear equations that characterize the low order harmonics are obtain...
