  • Load-segmentation-based 3-level inverter and method of controlling the same
    Patent number: 8902615
    Abstract: The present disclosure relates to a load-segmentation-based 3-level inverter and method for controlling same. Three-level inverter includes: multiple capacitors charged with voltages divided from a DC input voltage; top switch having one end connected with positive terminal of one of multiple capacitors; bottom switch having one end connected with negative terminal of one of multiple capacitors; multiple legs each including a first switch connected to the other end of top switch and a second switch connected to the other end of bottom switch with the first and second switches connected; multiple diodes connected in series forwardly from the other end of bottom switch to the other end of top switch and having interconnect points connected to a contact between the multiple capacitors; and multiple loads having connected terminals at a contact between the first and second switches of each of the legs and a contact between the multiple diodes.
