| Popis: | DC-link capacitors in power electronic converters are a major constraint on improvement of power density as well as reliability. Evaluation of the dc-link capacitors in terms of power loss, ageing, and failure rate will play an important role in design stages of the next-generation power converters. This paper proposes a new evaluation circuit for dc-link capacitors used in a high-power three-phase inverter, which employs a full-scale current-rating and downscale voltage-rating three-phase inverter, a low-voltage dc supply, and a high-voltage dc supply. The proposed evaluation circuit is equivalent to a full-scale current-rating and full-scale voltage-rating inverter from the standpoint of ripple current and dc bias voltage, whereas overall power rating of the proposed circuit is much smaller than that of the full-scale current-rating and full-scale voltage-rating inverter. 2015 IEE-Japan Industry Applications Society, September 2-4, 2015, Oita University, Oita, Japan |
