Abstract

In this paper a new diagnostic method utilizing the voltage across the output-filter inductor as diagnostic criterion is presented for the voltage-source inverters. This voltage can be easily obtained by adding a winding across the inductor, thus the sensor is needless and the diagnostic system is naturally isolated from the inverter. The average of the absolute voltage criterion in one period can be utilized to detect the open-circuit. To realize the method, one simple analog circuit is designed to process the voltage signal. Based on the proposed method, the diagnostic effective is independent of the loads and the cost of the diagnostic system is low. The method can be applied to both single-phase and three-phase inverter. The waveform analysis, diagnostic circuit design, and the experimental results are presented in this paper. The diagnostic method is fast, and the diagnostic system is low-cost.
