一种基于三柱芯变压器的三相AC-DC拓扑零净磁通调制方案

Existing single-stage 3-phase ac–dc isolated topologies typically use three separate C-core high-frequency transformers (HFTs), which require significant space and reduce power density. A key challenge preventing the use of a more compact 3-leg core HFT is the lack of suitable modulation schemes, as current methods do not ensure a zero net flux condition considering all 3 legs. Violating this cond...
