宽输入电压范围的间接输入串联直流变压器

To avoid fault hazards of the centralized capacitor on the high-voltage side, an indirect input-series dc transformer (I2S DCT) with a wide input voltage range is proposed in this article, where the input filter capacitors of adjacent cells are not directly connected in series. The high-voltage input side includes a boost inductor and N full-bridge cells and transformer primary windings. The trans...
