Optimization of selective harmonic eliminations

There's quite difficulty in acturalizing hardware while improving the quality and efficiency of output waveforms in the field of selective harmonic elimination technique. In order to solve this problem, an optimization scheme of omitting couples of switching angles or minimum pulses is presented, which can realize hardware easily, and reduce losses of switching transistors, then decrease the order of harmonics. All as above have been proved by theoretical analyses and calculations. The optimization scheme provides an effective means of applying selective harmonic elimination technique for projects.
