Abstract:
A relative maximum point and a relative minimum point, are provided in a first reactor current and a second reactor current within one control cycle as a result of control of on and off of switching elements. At least one of the inflection points in the first and second reactor currents, a plurality of switching elements to simultaneously be turned on or and off are controlled to be turned on or off in a prescribed order with a time lag being set. At the inflection point with the time lag being set, a switching loss is produced in a switching element turned on later or a switching element turned on earlier in accordance with the prescribed order.

Claim (Index 8):
A power supply system which controls a DC voltage between a first power line on a high voltage side and a second power line on a low voltage side, comprising:\n a first DC power supply; a second DC power supply; a power converter which carries out DC voltage conversion between the first and second DC power supplies and the first and second power lines; and a control device which controls an operation of the power converter, the power converter including\n a first semiconductor element electrically connected between the first power line and a first node, \n a first reactor electrically connected in series with the first DC power supply, between the first node and the second power line, \n a second semiconductor element electrically connected between the second power line and the first node, \n a second reactor electrically connected in series with the second DC power supply, between a second node and the first power line, \n a third semiconductor element electrically connected between the second node and the second power line, \n a fourth semiconductor element electrically connected between the first power line and the second node, and \n a fifth semiconductor element electrically connected between the first node and the second node, \n at least some of the first to fifth semiconductor elements each including a switching element which is configured to control formation and cut-off of a current path in response to a signal from the control device, each of a first reactor current which flows through the first reactor and a second reactor current which flows through the second reactor being controlled to have a plurality of inflection points in each control cycle as a result of control of on and off of the switching element in response to a control signal from the control device, the control device having a first switching control mode in which the control signal for the switching element is generated to turn on or off a plurality of the switching elements to simultaneously be turned on or off in a prescribed order with a time lag being set at at least one of the plurality of inflection points produced in the first and second reactor currents, and in the first switching control mode, at the inflection point with the time lag being set, a switching loss being produced in a switching element turned off later or a switching element turned on earlier in accordance with the prescribed order.
