This paper shows a method for optimization of CHB inverter's harmonic performance under Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) control. The optimization techniques are used for solving the set of non-linear transcendental trigonometrical equations. SHE is implemented to reduce the THD value. The set of non-linear equation is minimized by Big Bang-Big Crunch optimization technique...
The Objective of the paper is to reduce the harmonic order such as 5th, 7th, 11th, 13th, 17th, 19th and 23rd. The triplen harmonic like 3rd, 9th, 15th, 21st are eliminated naturally by three phase inverter. The proposed waveform is symmetric so that all even order harmonics will be eliminated. In order to reduce lower order harmonics, differential evolution optimization technique is used to find the...
