用于中压直流系统高频低dv/dt的多开关桥臂DAB变换器

The medium voltage (MV) high-power dc–dc isolated converter topologies are gaining huge interest as they offer high efficiency and power density. In the recent past, one of the major research areas for such system has been the reduction of rate of change of voltage ($dv/dt$) across the transformer windings and voltage stress across switches. This letter proposes a multiswitch-leg dual active bridg...
