摘要:
An electrical converter includes at least three AC terminals, a first and a second DC terminal and at least three converter modules. Each of the at least three converter modules has a first converter stage including a flying capacitor circuit coupled to a first switch node, a second converter stage including a flying capacitor circuit coupled to a second switch node, a first inductor, and a first capacitor. The first and second switch nodes are connected to opposite terminals of the first inductor. One of the at least three AC terminals and the second DC terminal are connected to opposite terminals of the first capacitor. The second DC terminal forms a star-point of the first capacitors. A flying capacitor voltage of the first converter stage is clamped to a first voltage across the first capacitor when the first voltage drops below the flying capacitor voltage.
