Impact of PWM strategies on RMS current of the DC-link Voltage Capacitor of a dual-three phase drive [PDF]
, 2014 The major drawback of usual dual three-phase AC machines, when supplied by a Voltage Source Inverter (VSI), is the occurrence of extra harmonic currents which circulate in the stator windings causing additional losses and constraints on the power ...

Decoupled DC-Link Capacitor Voltage Control of DC–AC Multilevel Multileg Converters [PDF]
IEEE Transactions on Industrial Electronics, 2016 This paper studies the coupling between the capacitor voltage control loops of diode-clamped (or functionally equivalent) multilevel multileg (multiphase) dc-ac converters. From a complete model of the plant revealing the coupling, a simple approach consisting in multiplying the vector of control commands by a constant matrix is proposed to decouple ...

Advanced Vector Controller for a Four-Switch Three-Phase Rectifier under Unbalanced Grid Voltage
International Transactions on Electrical Energy Systems, 2022 One of the main challenges of a four-switch three-phase rectifier (FSTPR) is a DC imbalance in capacitor voltages. On the other hand, under unbalanced grid voltage conditions, unbalanced three-phase input current and the DC-link voltage affect the ...
