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.

Optimization Tool for Dc-Link Capacitor Bank Design in PV Inverters

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
The development of a tool is presented for optimizing dc-link capacitors design in PV inverters. Reliability of power converters is well known to be one of the bottlenecks for decreasing the cost of renewable energy systems. Thus, this paper proposes an analysis and design method for estimating the lifetime performance of multiple capacitor bank ...

Comparison of DC-Link Capacitor Types Under Various Grid Conditions

2019 IEEE 13th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2019
A DC/AC converter can face negative conditions of power systems such as instability. One of the most crucial necessities of the grid is voltage stability. There are some effects of voltage unbalance for grid-tied DC/AC converters. Grid voltage unbalance causes higher THD values on grid currents than normal grid conditions.

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
