同伦新算法在逆变器消谐模型中的研究及应用

Study and Application of Homotopy New Algorithm in Inverter Harmonic Elimination Model

把基于割线预估、牛顿校正思想的路径跟踪新算法应用到逆变消谐问题中,通过与牛顿算法和原有同伦算法的比较和分析,得出新算法不仅收敛范围比牛顿法扩大了,且精确度也比原有同伦算法高.

A new algorithm is proposed based on secant prediction and Newton correction, and applied in inverter harmonic elimination model. Comparing with Newton algorithm and originally possessed homotopy algorithm, the new algorithm convergence domains are not only more than those of Newton algorithm, but also its precision makes a progress.
