Complete Fast Analytical Solution of the Optimal Odd Single-Phase Multilevel Problem
Original language description
In this paper we focus on computation of optimal switching angles for general multilevel odd symmetry waveforms. We show that this problem is similar to (but more general than) the PWM modulation problem which is an established method of generating PWM waveforms with low base-band distortion. We introduce a new general modulation strategy for multilevel inverters which takes an analytic form and is very fast with the complexity of only O(n log^2 n) arithmetic operations where n is the num. of controlledharmonics. This alg. is based on a transf. of appropriate trigonometric eqs. for each controlled harmonics to a poly. system of eqs. that is further transformed to a special sys. of composite sum of powers. The solution of this sys. is carried out by amodification of the Newton's identity via Pade approx., formal ortho. poly. theory, and properties of symmetric poly. Finally, the optimal switching sequence is obtained by computing zeros of two formal ortho. poly. in one variable.
