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.
