本文研究了消除逆变器输出波形中谐波的理论问题。广义方法的开发，用于消除固定数量的谐波在半桥和全桥逆变器输出波形，并提出了解决方案，用于消除多达五个谐波。应用数值技术在计算机上求解问题的非线性方程组。未消除的高次谐波可以很容易地通过在逆变器的输出级中使用滤波电路来衰减。结果表明，获得实际的正弦输出波形，这是非常可取的，在大多数逆变器应用的可行性。
This paper considers the theoretical problem of eliminating harmonics in inverter-output waveforms. Generalized methods are developed for eliminating a fixed number of harmonics in the half-bridge and full-bridge inverter-output waveforms, and solutions are presented for eliminating up to five harmonics. Numerical techniques are applied to solve the nonlinear equations of the problem on the computer. The uneliminated higher order harmonics can be easily attenuated by using filter circuits in the output stage of the inverter. The results show the feasibility of obtaining practically sinusoidal output waveforms, which are highly desirable in most inverter applications.
