Neutral-point potential oscillation and balancing problem is an inherent drawback hindering the extensively application of Neutral-Point-Clamped three-level converters. Based on the excellent performances of double signal PWM method contributing to the oscillation elimination, this paper proposes an improved neutral-point voltage balancing compensator. The validity and practicability of the proposed algorithm is verified by simulation and experimental results.
