Abstract
A three-level converter includes a first power switch, which has a first end connected to a first DC input end and a first end of a third power switch. A second end of a second power switch is connected to a second DC input end and a second end of a fourth power switch. A connection point between a second end of the first power switch and a first end of the second power switch is a first AC output end. A connection point between a second end of the third power switch and a first end of the fourth power switch is a second AC output end. Fifth and sixth power switches are connected in series between the first AC output end and a neutral end. A seventh power switch is connected between the second AC output end and a connection point between the fifth and sixth power switches.
