| Abstract: | This paper introduces PWM controller of the variant frequency and converting velocity based on MCS-51 single-computer and HEF4752 , analyzes effects and producing method of all control signal of the HEF4752 in detail . The controller has more generality and convenience to use, transistor and thyristor can be used by power element , parameter set and control operation can be finished on the key , the controller can be composed open-loop control system in single and close-loop control system with upper-computer . |
