Abstract

In this paper, the low-order harmonic elimination problem of H-bridge unit number 3 is explored with the cascade H-bridge converter. The initial value is calculated by using the method of vertical bisector reference sinusoidal signal, and then using the principle of least squares The Gauss-Newton method is iteratively solved, and the three switching angles are respectively, and the corresponding THD is 11.39%. Through the dichotomy to discuss the angle of the modulation ratio when the switching angle is resolved, the corresponding THD range is.
