We address the Selective Harmonic Modulation (SHM) problem in power
electronic engineering, consisting in designing a multilevel staircase
control signal with some prescribed frequencies to improve the
performances of a converter. In this work, SHM is addressed through an
optimal control methodology based on duality, in which the admissible
controls are piece-wise constant functions, taking values only in a
given finite set. To fulfill this constraint, the cornerstone of our
approach is the introduction of a special penalization in the cost
functional, in the form of a piece-wise affine approximation of a
parabola. In this manner, we build optimal multilevel controls having
the desired staircase structure.
