When nonlinear loads are put into operation at random phase Angle in power system, the superposition of harmonics should be considered.
当具有随机相角的非线性负荷投入系统运行时，应考虑谐波叠加的问题。

In the structure, the (equal) integration area method was used to determine the control switch Angle, and the sinusoidal voltage wave was obtained by means of the concatenate superposition.
该结构利用积分面积相等的原则确定开关角，通过串级叠加的方法得到标准正弦波输出。

Intelligent components of symmetrical arrangement improved the superposition place will appear in the process of heat circulation cooling blind Angle.
