摘要： Two semiconductor switches (Q1, Q2) are arranged in parallel in a load circuit for connecting a power source with a load. Further, the semiconductor switches (Q1, Q2) 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 (Q1, Q2), an offset error detected by current sensors (12, 22) 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 power conversion unit (50) includes an AC/DC converter (51) converting alternating-current power supplied from an AC power supply (2) into direct-current power to charge a high-voltage battery (30) with the direct-current power and a step-down DC/DC converter (52) generating an intermediate voltage (Vm) provided by stepping down a voltage of direct-current power supplied from the high-voltage battery (30). A constant-voltage DC/DC converter (60) outputs, to a low-voltage load unit (4), direct-current power provided by stepping down the intermediate voltage (Vm) of direct-current power output from the step-down DC/DC converter (52) at a constant step-down ratio.

摘要： A load circuit disconnection detector includes: a current sensor (16) for detecting current flowing through a wire (W1) of a load circuit; and a protective device (100) for estimating temperature of the wire (W1) based on the detected current and forcibly turning off a semiconductor switch (Q1) if the estimated temperature of the wire reaches threshold temperature. The load circuit disconnection detector determines that there is a connection failure in the load circuit if a temperature increase calculated by a temperature calculation unit (24) is zero even a predetermined time (P1) after the semiconductor switch (Q1) is turned on.

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 protection apparatus for a load circuit is provided which can miniaturize electric wires and semiconductor switches by using a switch circuit simulating the current · interruption time characteristics of fuses. A conductor resistance r and a heat resistance R used in each of a heat generation temperature calculation expression and a heat dissipation temperature calculation expression are respectively changed into a pseudo conductor resistance r* and a pseudo heat resistance R*, then the heat generation amount and the heat dissipation amount of the electric wire are calculated, and current temperature of the electric wire is estimated. When the estimation temperature reaches allowable temperature, an electronic switch S1 is turned off to thereby protect the load circuit. As a result, each of the electric wires and the semiconductor switches used in the load circuit can be protected from over heat.

摘要： In a power supply device (1), a common power supply terminal (32) has a shape connectable in common to a power supply terminal of a direct-current power supply (DC) installed outside a vehicle (V) and a power supply terminal of an alternating-current power supply (AC) installed outside the vehicle (V). An AC power supply line connects the common power supply terminal (32) and a battery (10) through an AC/DC conversion unit (60). A DC power supply line connects the common power supply terminal (32) and the battery (10) not through the AC/DC conversion unit (60). A controller (80) makes a switch to the DC power supply line when a power supply connected to the common power supply terminal (32) is the direct-current power supply (DC) and makes a switch to the AC power supply line when the power supply connected to the common power supply terminal (32) is the alternating-current power supply (AC) to charge the battery (10) with power input to the common power supply terminal (32).
