Three-phase Asychronous motor

AC-DC-AC双pwm逆变器的Matlab/Simulink仿真源程序。包括两个电路：一个是50Hz三相 AC(PWM整流)->DC->50Hz三相AC(PWM逆变),驱动三相对称电阻负载；一个是60Hz 三相AC(全波整流)->DC->50Hz三相AC（PWM逆变），驱动一个永磁同步电动机。（本源码基于王军(xiaohongchen@163.com)上载的double_pwm_inverter.mdl改进而来，适用于matlab7.3.0(R2006)版本）(AC-DC-AC inverter pwm dual Matlab/Simulink simulation source. Includes two circuits: one is the 50Hz three-phase AC (PWM rectifier)-)
