Abstract: A power converter is presented. The power converter includes at least one leg operatively coupled between a first bus and a second bus and includes a first string including a plurality of non-controllable semiconductor switches, a first node, a second node, and a third node, where the first node is coupled to a third bus, one or more second strings, where each of the one or more second strings includes at least one fully controllable semiconductor switch, and where one of the second strings is coupled between the first node and the third bus and another second string is coupled between the second node and the third node, and one or more third strings, where each of the one or more third strings includes at least one energy storage device and is coupled to the first string, the one or more second strings, or a combination thereof.

Abstract: A converter includes a first converter module and a second converter module coupled to the first converter module in a nested manner. Each of the first converter module and the second converter module includes a plurality of switch units. When the converter is operated to perform power conversion, at least two of the plurality of switch units is configured to be switched both in a complementary pattern and a non-complementary pattern.
