摘要：
This paper proposes a condition monitoring scheme for DC-link electrolytic capacitors used in regenerative medium power converters. The monitoring scheme is based on capacitor bank voltage measurements in quasi-offline mode. The aim of this work is to identify the voltage measurement precision and sampling requirements to enable a reproducible and reliable capacitance calculation. The proposed method is analysed theoretically and supported by simulation results and validated experimentally.
