This paper discusses about an algorithm of calculating the pulse switch Angle by using of forward network BP algorithm based on the Neural network, and makes the MATLAB simulation.

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.

Like a giant discus landed at an Angle or an enormous light switch, Alexandria's oceanfront library is arguably the first great design of the new millennium.
