Multibattery charger system based on a multilevel dual-active-bridge power converter

This work introduces a novel battery charger implemented with a four-level three-phase neutral-point-clamped converter and a four-level single-phase dual-active-bridge converter, which offers the intrinsic advantages of multilevel conversion, provides galvanic isolation and allows bidirectional powe...
