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.
