if i want to eliminate 3,5 harmonics in a 2 level inverter, there are 3 angles generated using selective harmonic elimination. how do i implement this extra angle generated as it has only 2 levels. ?
Hi
There are lot of papers which discuss similar situations. For example, please have a look at the following paper:

Dear Researcher,
Please consider the following recent SHE techniques:
A. K. Kaviani, S. H. Fathi, N. Farokhnia, and A. J. Ardakani, “PSO, an effective tool for harmonics elimination and optimization in multi-level inverters,” in Proc. IEEE 4th Conf. Ind. Electron. Appl., Xi’an, China, 2009, pp. 2902–7.
In particular read the following paper
A. Kavousi, B. Vahidi, R. Salehi, M. Bakhshizadeh, N. Farokhnia, and S. S. Fathi, “Application of the bee algorithm for selective harmonic elim- ination strategy in multilevel inverters,” IEEE Trans. Power Electron., vol. 27, no. 4, pp. 1689–96, Apr. 2012.
V. Roberge and M. Tarbouchi, “Efficient parallel particle swarm optimizers on GPU for real-time harmonic minimization in multilevel inverters,” in Proc. IEEE38th Annu. Conf. Ind. Electron. Soc., Montreal, Canada, 2012, pp. 2275–2282.

These are very good references:

simply by switching a number of times, at required angle(s), in both positive and negative levels. This way a 2Level waveforms will have several notches created by these switching actions.
