Abstract
According to one embodiment, an electronic circuitry that converts DC voltage into AC voltage includes first to fourth switching circuitries. A cycle includes first and second periods. During the first period, the first and second switching circuitries are turned on, and the third and fourth switching circuitries are turned off, and during the second period, the first switching and second circuitries are turned off, and the third and fourth switching circuitries are turned on. At least one of the first to fourth switching circuitries includes a first switching element and a second switching element in parallel. During a time period during which at least one of the first to fourth switching circuitries is turned on, the first switching element is turned on during a first subperiod, and the second switching element is turned on during a second subperiod that overlaps the first subperiod.
