Active voltage balancing of DC-link electrolytic capacitors
IET Power Electronics, 2008 DC voltage links of three-phase power converters are frequently equipped with a series connection of two electrolytic capacitors because of high voltage level. For such a configuration, usually resistors have to be arranged in parallel to each capacitor in order to balance the partial voltages. These balancing resistors, however, have to be dimensioned

Virtual inertia with PV inverters using DC-link capacitors [PDF]
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016 Soon, virtual inertia for grid control must be covered by photovoltaic inverters. It is suggested to use DC link capacitors for this task. This requires 5 W, 50 J and a capacitor size of about 200 cm3 per installed kW, corresponding to the size of single phase DC link capacitors. It is shown that the additional power ripple (and thus current ripple) is
