Abstract
A 3-level power converter is provided, which is reduced in size of the converter, reduced in floating inductance of each of wirings interconnecting between respective elements, and easily attached with a snubber circuit. The 3-level power converter performs on/off control of first to fourth switching elementstoso as to output a 3-level voltage from an AC output terminal AC, wherein the power converter has a first moduleincluding the first and fourth switching elementsandas a configuration unit, a second moduleincluding the second and third switching elementsandas a configuration unit, a third moduleincluding a first coupling diodeas a configuration unit, and a fourth moduleincluding a second coupling diode as a configuration unit, and the second module, the fourth module, the third module, and the first moduleare sequentially arranged in a line from a position near the AC output terminal AC.
