Abstract

The problem of eliminating harmonics with total harmonic distortion minimizing in a switching converter is considered. Existing popular methods for solving the problem were analyzed. Conventional implementations of harmonic elimination technique given not all possible solution to this problem. In this paper, the basic algebraic properties of the optimal pulse modulation problem for single-phase inverters are revealed. A new solution of this problem based on straight-line searching method and properties of symmetric functions was proposed. The result for bipolar pulse modulation scheme to eliminate the 3th harmonic was presented.
