摘要： Two semiconductor switches are arranged in parallel in a load circuit for connecting a power source with a load. Further, the semiconductor switches are controlled so as to be alternately tuned on and off. As a result, since a current flows through only either of the semiconductor switches, an offset error detected by current sensors includes only an offset error of either of the semiconductor switches, the detection of current with high accuracy can be accomplished. Therefore, when performing the control of shutting off the circuit to cope with the occurrence of an overcurrent flowing through the load, the shutoff control with high accuracy can be accomplished.

摘要： A load circuit protective device calculates increasing temperature of wire of a load circuit with a first predetermined sampling period (dt1) determined by a clock signal for normal operation when a semiconductor relay (Q1) is on to estimate the temperature of the wire. The temperature of the wire is therefore estimated with high accuracy. Moreover, when the semiconductor relay (Q1) is off, the load circuit protective device calculates decreasing temperature of the wire of the load circuit with a second predetermined sampling period (dt2) to estimate the temperature of the wire. The second predetermined sampling period (dt2) is determined by a clock signal for power-saving operation and is longer than the first predetermined sampling period (dt1). Accordingly, the calculation times of the temperature can be reduced, and the power consumption is therefore reduced.

摘要： An electric power distribution device sets a first threshold and a second threshold for a threshold temperature of main wires, and sets a third threshold and a fourth threshold for a threshold temperature of branch wires. In the case where a temperature of each of the main wires reaches the first threshold, all of branch wire switches provided in a branch wire distributor are shut off. Thereafter, in the case where the temperature of the main wire reaches the second threshold, each of the main wire switches, which is provided a main wire distributor, is shut off. In the case where a temperature of a certain branch wire reaches the third threshold, the corresponding branch wire switch is subjected to PWM control. Thereafter, in the case where the temperature of the branch wire reaches the fourth threshold, the corresponding branch wire switch is shut off.

摘要： A controller 43 turns on a semiconductor switch 41 in a normal mode, and turns off the semiconductor switch 41 in a sleep mode. A bypass resistor 5 is connected in parallel to the semiconductor switch 41. A resistance value of the bypass resister 5 is so large as that in the sleep mode, a dark current is supplied to an electronic device 3 via the bypass resistor 5, and if an electric wire downstream of the bypass resistor is short-circuited, an electric current more than a permissive current is prevented from flowing to the electric wire.

摘要： A switch operating unit 10 has operating switches for operating loads. A load control unit controls the corresponding loads in accordance with the operation of the operating switches according to information, which is stored in first storage device, as to the correlation between the operating switches and the loads. A total rated capacity computation device computes the total rated capacity of the loads to be driven under the control of the load control unit according to information, which is stored in second storage device, as to the rated capacity of each load. When the total rated capacity exceeds a predetermined allowable capacity, the load control unit operates to restrict the driving of the low-priority loads in the order of analog-controlled loads and on-off controlled loads according to the information stored in the second storage device.
