Application of Complexity Measure Analysis to Power Electronic Circuit Fault Prediction

电力电子设备在线故障分析是人们十分关注的课题,科技工作者在这方面常遇到许多困难。复杂性是对研究对象复杂程度的客观度量。本文分析了电路故障的混沌特性,借助这种新的复杂性分析的方法,利用综合性信号监测电路状态,可作为系统可靠性预测的手段。

Under the condition of high-voltage, heavy-current and high-frequency, it is a rather difficult to inspect and supervise the electric circuits. For this reason, a new method called complexity measure analysis is proposed to inspect the circuit fault status by analyzing synthetic signal. Compared with the traditional method, the proposed method has the advantages as high speed, easy operation, less expenses, safety, non-destruction, etc. It also can be used as a reliability predicting measure for electric circuit systems.
