Improve the power density of traditional Modular Multilevel Converter (MMC) exploited in medium voltage motor drive.
- High Power density: 30% higher compared with Traditional MMC (30%~40% less capacitor size ue to the 50% energy ripple reduction.);
- High Scalability: easily scaled up and down by adding or removing some modules according to different requirements.
- Low EMI: relatively small module level dv/dt and carefully designed Dclink busbar(minimized parasitic).
