Application of Newton Identities in Solving Selective Harmonic Elimination Problem With Algebraic Algorithms

Algebraic algorithms are powerful methods in solving the selective harmonic elimination (SHE) problem, which can find all exact solutions without requirements of choosing initial values. However, huge computational burden and long time limit capability algebraic algorithms. This article presents a novel Newton’s identifies-based method to simplify SHE equations including order reduction variable elimination, thereby reducing or other words improving Compared with existing simplification methods, proposed significantly improves efficiency equations. With method, degree is no longer bottleneck by using By ten switching angles completely solved algorithm for first time. The simulation experimental results indicate that effective correct.
