Abstract:
A power source device comprising:at least first and second power converting circuits,said first power converting circuit including first switching means for opening and closing a current path in response to driving signals, a first rectifying means and a first inductor, and said second power converting circuit including second switching means for opening and closing a current path in response to the driving signals, a second rectifying means and a second inductor; anda control circuit connected to the first and second power converting circuits for performing at least one of an inverse parallel connection of and a common use with the switching means incorporating a rectifying element of at least a set of the first switching means and second rectifying means and of the second switching means and first rectifying means, to generate at least one of the driving signals for closing the first switching means in a period in which the second rectifying means is conductive and for closing the second switching means in a period in which the first rectifying means is conductive in an event when neither of the inverse parallel connection and the common use is performed.
