Abstract

Electrolytic capacitors with a DC-side inductor, and the slim DC-link capacitor are two typical filtering configurations in Adjustable Speed Drives (ASDs). The reliability performance of these capacitive DC-link solutions is an essential aspect to be considered, which depends on both component inherent capability and the operational conditions (e.g., electro-thermal stresses) in the field operation. This paper studies the reliability performance of the LC filter and slim capacitor based filter in a standard ASD system. Considering the variations of the capacitor parameters, environment stresses, and lifetime model, the lifetime of the two configurations are compared. Moreover, scalability analysis is presented in terms of power rating, amplitude and phase angle unbalance levels at the grid side. The results serve as a guideline for reliability aspect performance benchmarking of different DC-link solutions in ASD applications.
