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）

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.
