Objective

Improve the power density of traditional Modular Multilevel Converter (MMC) exploited in medium voltage motor drive.

Features

  • 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).

Applications

HVDC/MVDC/Motor Drive
