Abstract: This paper illustrates a way to verify optimised angles for five and seven level single-phase inverters. The ability to follow strict angles for switching times is due to a simple synchronising scheme used along with the arctangent method. Power stage is focused to attain the lowest number of switches and DC sources, and can be used in a cascade multilevel strategy. Comparison of harmonic contents and total harmonic distortion is presented for several optimisation strategies carried out on the literature, and a compensation scheme for regulation with two degree of freedom that brings the inverter to have 11 or 15 level and be within the standard is proposed.
