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.

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.
