Abstract
Under the same target voltage, a basic duty ratio depending on a target ON time is set, and prior and subsequent duty ratios before and after upper arm switching devices or lower arm switching devices are driven with the basic duty ratio are set as a basic duty ratio+α and a basic duty ratio−α, respectively. Gate drive signals, having the basic duty ratio and the prior and subsequent duty ratios, are supplied to the upper arm switching devices or to the lower arm switching devices, in order to turn on the upper arm switching devices or the lower arm switching devices.
