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.

Comparison of DC-Link Capacitor Types Under Various Grid Conditions
2019 IEEE 13th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2019A 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.

The impact of grid unbalances on the reliability of DC-link capacitors in a motor drive
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017DC-link capacitor is one of the reliability-critical components in motor drive applications, which contributes to a considerable cost, size and failure. Its reliability performance depends on both inherent physical strength and external loading. The grid unbalances could alter the electro-thermal stresses of key components in a motor drive.

Reliability of DC-link capacitors in power electronic converters
2015DC-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
