Early diagnosis in DC-link capacitors: electrolytic and films

2018
This chapter presents an RUL prediction algorithm based on accelerated life test data and derived physics models for electrolytic capacitors. The main elements are (1) development of the first principles based degradation models; (2) the implementation of a Bayesian-based health state tracking and RUL prediction algorithm based on the Kalman filtering ...

DC-Link Voltage Fluctuation Reduction of Vector Controlled PMSM Drives with Reduced DC-Link Capacitor

2018 IEEE 4th Information Technology and Mechatronics Engineering Conference (ITOEC), 2018
In some applications, to increase the system power density and lower the system cost, the dc-link capacitance of PMSM drives needs to be reduced. However, such practice may cause considerable dc-link voltage fluctuation. In this study, a method is proposed to reduce the dc-link voltage fluctuation.

Reliability of DC-link capacitors in power electronic converters

2015
DC-link capacitors are widely used in power electronic converters to balance the instantaneous power difference between the input source and output load and to minimize voltage variation in the DC-link. In some applications, they are also used to provide energy storage. Figure 3.1 shows some typical configurations of power electronic conversion systems
