This paper proposes a new Modular Multilevel Cascade Converter (MMCC) topology for future high density medium-voltage motor drive. The proposed topology utilizes the active ripple energy storage method for rectifier capacitance design. Simulation has been done in this paper and proves that the proposed topology works well, and the active energy storage method can significantly reduce the DC-link capacitor. Power density improvement is quantified for an example system to show the benefits of the proposed topology.
