不平衡双极性直流微电网中Buck三电平DC-DC变换器的转换效率

This article evaluates the power conversion efficiency of the buck three-level dc–dc converter, when operating in unbalanced bipolar dc microgrids. Bipolar dc microgrids adopt a positive, neutral, and negative wire to double the power transfer capability, reduce conduction losses, and provide two voltage levels. Additional converters are however required to balance the pole-to-neutral voltages in ...
