摘要： A load current control apparatus according to the present invention includes a current detecting circuit adapted to detect an electric current on a power supply line used to supply electric power from a power supply unit to a load device, a field effect transistor adapted to turn on and off the power supply line, and a controller adapted to control the field effect transistor according to the electric current on the power supply line, in which the controller starts counting time from a time point when the electric current on the power supply line exceeds the overcurrent detection threshold while maintaining the field effect transistor in an ON state, sets an upper limit time corresponding to the electric current on the power supply line at that time as a time threshold based on a relationship between electric current and time set beforehand according to electrical characteristics of the field effect transistor, and turns off the field effect transistor when a time period corresponding to the time threshold elapses.

摘要： A coil device includes two core members, one of which is E-shaped. The E-shaped core member has left and right side faces, and a center leg that extends in a vertical direction. A conducting wire is wound around a core, the core being composed of the two core members arranged to face each other in the vertical direction with a gap between the two core members. The conducting wire is wound around the center leg. First and second heat-sinking plates made of metal are bent so as to be in contact with upper and side faces of the core. The first and second plates are arranged so that first edges of the plates are placed left-right symmetrically with respect to the core with a gap between the edges. Second edges of the plates are in contact with a metal heat-sinking board where the core is placed.

摘要： In a balance correction circuit including a plurality of converter type balance correction units that control a supply of a current to a plurality of power storage cells by complementarily on/off controlling two switching elements and hereby allowing to exchange power between or among power storage cells via an inductor to equalize the voltages of the power storage cells, a common timing signal used to generate a control signal of a switching element is supplied to each of the above balance correction units. For example, the balance correction circuit generates a timing signal to supply to a first balance correction unit based on a variation in a voltage applied to the capacitive element charged by a voltage difference created between a control signal generated by the second balance correction unit and a second power storage cell cathode of the balance correction unit.
