中文说明：采用加权网络中节点强度和权重都是幂率分布的模型，使用大量的有限元法求解偏微分方程，重要参数的提取，对于初学matlab的同学会有帮助，基于SVPWM的三电平逆变的matlab仿真，毕业设计有用。
English Description：
The weighted network node strength and weight are power-law distribution model, using a large number of finite element method for solving partial differential equations, parameters extraction, for the beginner will help matlab students, matlab simulation of SVPWM for three-level inverter based on graduation design useful.
