单相输入串联输出并联固态变压器的有源功率解耦

Solid-state transformers with input–series–output–parallel structures are being considered for a variety of applications requiring medium-voltage alternating current (MVAC) to low-voltage direct current (LVDC) conversion. Due to the single-phase ac–dc conversion at the input side, all floating cells of the solid-state transformer suffer from the well-known second harmonic pulsating power. Large dc...
