Abstract
This paper presents a reliability analysis of a three-leg four-wire inverter used to emulate non-linear loads. The converter under study can control the current per phase independently up to a maximum frequency of 650 Hz. A reliability analysis of the converter is carried out analyzing the effect of unbalanced loads and harmonic injection in the reliability of the semiconductors and capacitors. The results obtained show a faster degradation with the scenarios presented. The effect of the harmoni...
