| Abstract: | In order to implement the synchronous control of motor,a method for three-phase AC voltage zero-point inspecting and phase sequence self-adaptation is proposed in this paper.The micro-controller of P87C591 is the key part of the solution,the 6N137 and capture interrupt of P87C591 is adopted to detecting the zero-point of three-phase AC voltage.The phase sequence judgment and phase sequence self-adaptation is realized by the program operating in the controller.The software and hardware of the design method i... |
