摘　　要：:提出了逆变器消谐模型求解的同伦算法 ,分析了消谐模型的建立、同伦映射的特点及同伦方程的求解方法 ,研究了在具体应用中同伦算法的优化步骤 ,给出了算例 ,证明了此方法的正确性。该研究表明 :采用同伦算法进行逆变器消谐模型的求解 ,具有收敛范围宽、收敛速度快等显著优点 ,若能进一步提高硬件的运行速度 。The Homotopy algorithm of the inverter harmonic elimination model is presented and the problem must be solved to gain Homotopy mapping is analysed in this paper. The converagence of solutions of the gained Homopoty equations is analysed. Examples proved this method is correct. The results show that Homopoty algorithm used to solve the inverter harmonic elimination model has many excellency such as large converagence margin, quick converagence, insensitive initial iteration etc.If Homopoty mapping is felicitous and calulation speed is high, the real time harmonic elimination PWM control is possible.
