基于开关单元插入式直接交流-交流变换器与多绕组变压器的串联双极混合电压优化器

This article proposes a series bipolar hybrid voltage optimizer (B-HVO), which can work at the noninverting and inverting modes for addressing voltage sag/swell in the utility grid. The superiority of the proposed system is that the direct ac–ac converter cell is deeply integrated with the multiwindings line frequency transformer, which not only effectively diminishes the switches quantities, but ...
