Abstract
The present invention relates to a semiconductor device provided with a dead-time generation circuit, the semiconductor device including: first and second status-detection circuits that each have a function of detecting whether first and second switching devices are in turn-off operation to output first and second status signals, respectively, and each have a function of generating a dead time of on-off operation of the corresponding one of the first and second switching devices; a first logic circuit that receives a first on-off command signal instructing the first switching device to be turned on or off, and the second status signal to output a signal allowing the first switching device to be turned on only when the second switching device is not in turn-off operation; and a second logic circuit that receives the first on-off command signal instructing the second switching device to be turned on or off, and the first status signal to output a signal allowing the second switching device to be turned on only when the first switching device is not in turn-off operation.
