Original Abstract

This paper presents a design for a nested neutral point piloted (NNPP) converter. The proposed design incorporates redundant control of each power stage and additional sensing and control circuitry required to implement a fault tolerant operation. Additionally, an active capacitor voltage balancing technique is proposed and implemented to enhance the converter's volumetric density and improve the output harmonics by mitigating capacitor voltage imbalance. Simulation results validate the effectiveness of the proposed design. Hardware prototype is designed and is currently being assembled.
