摘要
对基于脉冲激励检测非工作相电流的方法进行了理论分析，提出对两非工作相施加脉冲激励，比较其响应电流变化以确定换相点的方法，通过仿真分析证明了该方法的有效性。运用该方法设计了位置检测器，并进行了实验研究，在不同转速下的实验结果证明该方法具有较高的可靠性和实用性。
This paper analyzes the method of non-conducting phase current detection based on voltage pulse in theory. A method is proposed by which a sequence of voltage pulses are applied to the two non-conducting phases and the corresponding current are compared to fix the point of phase changing. Simulation analyses prove that the proposed method is effective. An instrument of position detection is designed and tested. The test results prove that the proposed method has high reliability and utility.
