| Abstract: | A variable frequency speed control system of induction motor using a singlechip microcomputer MCS8098 is introduced.It uses HEF4752 to get SPWM pulses.The desired clock pulses can be generted by the aid of phaselocked frequency synthesis method,which is digltally controlled by a microcomputer.The intelligent power modules IPM are selected to use as its main switch components.The system is a PI closed loop control system and it has many other useful functions too.Experimental results show that the system has many progresses on reliability,accuracy and adaptability,etc. |
