    摘要： A triangular-wave current flows through a reactor of a DC/DC converter for converting voltages between increased and reduced levels. Surges are reduced, which are developed in an output voltage serving as a control voltage when the triangular-wave current changes across a zero value at which the current direction is changed. When a primary current flowing through the reactor changes across 0 [A] (zero value) at which the direction is changed, within an adjustment range, a feedback coefficient by which to multiply the error between the control voltage and a target voltage is multiplied by k (k>1) so as to increase a feedback amount. Surges developed in the control voltage due to a dead time when the primary current changes across 0 [A] are reduced.

    摘要： If a lower arm device connection period is non-zero in a previous switching cycle, a first dead time is prohibited from decreasing, and if the lower arm device connection period is zero, the first dead time is allowed to decrease, wherein the first dead time is the dead time provided after the lower arm device connection period in the previous switching cycle but before an upper arm device connection period in the current switching cycle.

    摘要： The two ends of a battery circuit (18), in which a first power supply (11) is connected in series to a second power supply (12), are connected to the respective first and third lines (L1 and L3), while a junction (18a) between the first power supply (11) and the second power supply (12) is connected to a second line (L2). The two ends of a switching circuit (33) are connected to the respective first and third lines (L1 and L3). An end of a reactor (34) is connected to a junction between first and second switching elements (31 and 32), while the other end of the reactor (34) is connected to the second line (L2).The power supply apparatus (10), when activated, executes an operation in which, while the ON state of the first switching element (31) is inhibited, only the second switching element (32) is alternately turned ON and OFF with the ON state duration changed such that the ON state duration has a tendency to become longer. Thereafter, the power supply apparatus (10) executes an operation in which the switching elements (31 and 32) are alternately turned ON.
