三相电源过零信号检测及相序自适应的研究与实现

Research and Implementation of Three-phase Supply Zero-Crossing Detection and Phase Sequence Self-adaptation

为了加强电机的同步控制力度,当前提出了一种获取三相交流电的电压过零信号和电源相序自适应方法。本文就三相电源过零信号检测做出简单的论述,并且就其实现相序自适应进一步研究,期望能够有效地推动我国电力相关行业的进一步发展。

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 order to promote the further development of China＇s electric power and re- lated industries, this paper discusses three-phase AC voltage zero-point inspecting and studies phase sequence self-adaptation.
