Abstract

A method is given to determine conditions for which the switching angles in a multilevel converter can be chosen to produce the required fundamental voltage while at the same time cancel out higher order harmonics. A complete analysis is given for a 7- level converter where it is shown that for a range of the modulation index m_I, the switching angles can be chosen to produce the desired fundamental V₁=m_I(s4V_dc/π) while making the 5^th and 7^th harmonics identically zero.
