	For designing a 35 level inverter with selective harmonic elimination method all triplen harmonics are eliminated due to delta connection and 5,7,11,13...49 harmonics will be cancelled by selecting proper firing angles. I formulate NR method for findings the firing angles. But due to initial guess programming can not solved correctly. Please let me know how can I solve 17 equations with correct initial guess?

	I was having a pretty good day until I figured out that your response is a serious answer and I have no idea what you posted.

	Maybe this will help: https://www.researchgate.net/publication/262642992_Elimination_of_Harmonics_in_Multilevel_Inverters_Connected_to_Solar_Photovoltaic_Systems_Using_ANFIS_An_Experimental_Case_Study Try a simpler case first (fewer levels).
