摘　　要：介绍dsPIC30F4012芯片,研究了dsPIC30F4012芯片在交流变频调速中的应用。本系统使用交-直-交电压型主电路,采用SVPWM技术,选用dsPIC形成PWM波,使用智能功率模块PW100CVA120作为逆变器主电路,给出了基于dsPIC的全数字实现及其实验波形。The dsPIC30F4012 microprocessor is introduced. The study of application in variable frequency drive system with dsPIC30F4012 is done. In this system , main circuit of AC-DC-AC voltage type frequency conversion is used; SVPWM technology rule sampling is adopted; dsPIC30F4012 is selected to form SPWM wave; and the IPM-PM100CVA120 is used in the main circuit of inverter. The full digital control scheme and the experimental results are given.
