Safe Operating Area of DC-Link Film Capacitors
IEEE Transactions on Power Electronics, 2021 This letter proposes a Safe Operating Area (SOA) concept for film capacitors in DC-link applications. The SOA is presented by capacitor voltage and ripple current, considering the impact of ambient temperature, degradation, and parameter variance. The theoretical derivations and proof-of-concept experimental verifications are given.

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 ...
