Neutral-Point Voltage Balancing Method for Three-Phase Three-Level Dual-Active-Bridge Converters
Three-phase three-level dual-active-bridge (3L-DAB3) converters are a potential topology for high-voltage and high-power applications. Neutral-point voltage balancing is a complex and important issue for three-level (3L) circuits.
