Decoupled DC-Link Capacitor Voltage Control of DC–AC Multilevel Multileg Converters [PDF]

open access: yesIEEE 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 ...

Multi‐phase VSI DC‐link capacitor considerations

open access: yesIET 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.
