Sizing DC-link Capacitors in Complex Automotive High Voltage Systems

2019 7th International Youth Conference on Energy (IYCE), 2019
In the high voltage (HV) supply systems of battery electric vehicles (BEV) current oscillations as conducted disturbances are present due to the switching operation of the power electronic devices. These oscillations have a great impact on the power quality and influences the availability and efficiency of the system operation.

Review on DC link capacitor issues in variable frequency drives

2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT), 2017
The dc link capacitor is an important energy storage device and also filter out the ripple voltage and current. The main dc link capacitor issues are the size, heating of the capacitor, voltage stability, increases the temperature in the device. This component also maintains the high reliability and long life.

Reliability Comparison of DC Link Capacitor Bank for Different Configurations

2019 IEEE International Conference on Industrial Technology (ICIT), 2019
A single phase grid connected solar Photovoltaic (PV) inverter requires capacitor banks as an energy buffer at a dc-link. The capacitor bank consists of Aluminum Electrolytic Capacitors (AECs), which are prone to early failure due to various electrical and environmental stresses.

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
