电机控制集成电路的选用 第八讲 三相正弦脉宽调制器SA838的应用

Selection and Operation of Integrated Circuit for Motor Control —Lecture Enghth· Application of Three Phase SPWM Device SA838

由于交流变频调速越来越得到广泛应用 ,对高精度高集成度 SPWM产生器的要求也就越来越高。文中就三相正弦脉宽调制器 SA83 8的特点、功能以及参数设定作以说明 。

As the application of AC variable frequency speed regulation is widely popularized, the request of high precision and high integrality about SPWM generator becomes higher.The paper will introduce the characteristic, function and parameter calculation of SPWM generator SA838, as the same time provide a type application about SA838.
