Abstract

See full text

A power converter includes a group of serial three-level inverters including 2n (n=2) three-level inverters connected in series, two switch circuits for selecting an output from either one of two of the three-level inverters in the group of serial three-level inverters, and a switch circuit for selecting an output from either one of the switch circuits. Each three-level inverter includes two switch elements connected in series, two capacitors connected in series, and a switch element for connecting the first node to the second node, the switch elements being connected in parallel to the capacitors.
