    摘要: A method protects a battery in a fuel cell vehicle, in which an inverter-driven motor is supplied with electric power from the battery and a fuel cell. If a battery voltage of the battery falls outside of a prescribed range, a primary current and a secondary current that flow through the DC/DC converter, or currents in branch paths that correspond to the primary current and the secondary current, are reduced in order to limit a charging current flowing into the battery or a discharging current flowing from the battery.

    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: A redundant communication system includes a first control device which calculates a control command value of an electric power device, and outputs first and second command signals; a second control device which controls the electric power device on the basis of one of the first and second control command values; and primary and secondary communication lines for respectively transmitting the first and second command signals to the second control device. The second control device comprises: a primary communication line abnormality determining unit which determines that the primary communication line is abnormal when a non-reception state or an abnormality state of the first command signal continues during a predetermined period; and a control command value switching unit which selects one of the first and second control command values in a switching manner and switches the selection from the first to the second control command value within the predetermined period.
