Abstract |
|
This paper represents the reduction of harmonics in a cascade H-bridge multilevel inverter using iterative newton-raphson (NR) and genetic algorithm (GA) techniques. The proposed optimization techniques are used to solve the set of non-linear transcendental trigonometrical equations. The controlling pulses are obtained by harmonic elimination pulse width modulation (SHE-PWM) switching method. The set of non-linear transcendental equation is minimized by proposed iterative newton-raphson (NR) and genetic algorithm (GA) techniques, and also have been analysed and compared the harmonics. |
