A Torque Control Method Based on
IEEE Access, 2021 In traditional motor drive system, large volume electrolytic capacitors are utilized to buffer energy and stabilize the dc-link voltage. However, these capacitors affect the reliability of the drives and narrow the conduction angle of diode-rectifier. As

A control strategy for a three-phase four-wire shunt active filter [PDF]
, 2008 This paper presents a control strategy for a three- phase four-wire shunt active filter. The shunt active filter is a custom-power device capable to compensate, in real time, harmonics, unbalances and power factor in an electrical installation.

Multi‐phase VSI DC‐link capacitor considerations
IET Electric Power Applications, 2019 The modelling, control, switching schemes, novel applications, etc. of multi‐phase voltage source inverters (VSIs) have been studied in recent years. While some DC‐link capacitor considerations have been reported and ripple current assessments presented, the impact of these analyses on system design has not previously been quantified.

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
