Homotopy-Based Computation for Harmonic Elimination in PWM Inverters

讨论了逆变电源特定消谐技术的特点；以单相全桥电压型逆变电源为分析对象，研究了特定消谐技术的数学模型及其非线性方程组的同伦法求解方法；并用实例进行分析，通过计算机仿真，说明了该方法的特点。它的优点为实时控制提供了可能性。

Programmed pulse - with modulators (PWM'S), which eliminating several low - order harmonics to generate high -quality output spectra necessitates soving systems of nonlinear equations.Conventional implementations of this technique based on storing off - line calculated soutions have the common problem that the system flexibility is very limited. A new method of solving the nonlinear equations quickly is illustraed in this letter. This method permits the use of real - time solution control.
