本文对传统三相电压型逆变器的故障运行进行了调查和综合分析。在介绍电力电子技术中功率变换器可靠性和故障分析问题的介绍部分之后，介绍了一种兼顾健康和故障条件的广义开关函数以及一种在控制算法中嵌入故障诊断和重新配置的简单可行的方法。所提出的系统具有简单和紧凑的实现。在开环和闭环电流控制下运行的实验结果表明，所提出的解决方案是有效可行的，并使控制器本身易于管理所有故障。
This paper presents an investigation and a comprehensive analysis on fault operations in a conventional three-phase voltage source inverter. After an introductory section dealing with power converter reliability and fault analysis issues in power electronics, a generalized switching function accounting for both healthy and faulty conditions and an easy and feasible method to embed fault diagnosis and reconfiguration within the control algorithm are introduced. The proposed system has simple and compact implementation. Experimental results operating both at open- and closed-loop current control, obtained using a test bench realized using a dSPACE system and the fault-tolerant inverter prototype demonstrate that the proposed solution is effective and feasible and makes all faults easily managed by the controller itself.
