摘要： A current sensor is configured such that at least one magnetoelectric conversion element, a conductor, a signal processing IC, an IC supporting portion, and an element supporting portion are encapsulated with an encapsulating portion. The current sensor is comprised of a pair of first lead terminals that is partially exposed outside the encapsulating portion, is electrically connected to the conductor, inputs a measurement current to the conductor, and outputs the measurement current from the conductor; and a metal member that is partially exposed outside the encapsulating portion and is spaced apart from the conductor. The element supporting portion further supports the metal member on a surface on the same side as a first surface on which the IC supporting portion supports the signal processing IC.

摘要： A current sense circuit includes channels a detection terminal, a feedback circuit and third-type switches. The channels respectively have first-type switches and second-type switches. Each of the first-type switches supplies an electric power to a load when the first-type switch is turned on. The second-type switches are respectively connected to the first-type switches in parallel, and respectively detect currents flowing through the first-type switches. The detection terminal is connected to the second-type switches. The feedback circuit includes a single operational amplifier having a first input terminal and a second input terminal. The first input terminal is connected to respective electrodes of the first-type switches close to the load. The second input terminal is connected to respective electrodes of the second-type switches close to the detection terminal. The third-type switches are connected to the electrodes of the first-type switches and the first input terminal.

摘要： A vehicle electric power control apparatus includes semiconductor fuses, current sensors, an interlayer short-circuit determination unit, and a switching unit. The semiconductor fuses are disposed between a vehicle power supply and respective vehicle auxiliary devices. The current sensors detect current values flowing through the respective semiconductor fuses. The interlayer short-circuit determination unit makes a determination as to occurrence of an interlayer short-circuit between any of the semiconductor fuses and a corresponding one of the vehicle auxiliary devices, on the condition that a second current detection value inputted from the corresponding one of the vehicle auxiliary devices differs from an allowable value of a first current detection value inputted from a corresponding one of the current sensors. The switching unit switches, to off-operation, the any of the semiconductor fuses on a path related to the determination as to the occurrence of the interlayer short-circuit.

摘要： The present disclosure relates to an electrical circuit arrangement comprising an inverter and a measuring device designed to identify a short circuit between a conductor and a shielding in a circuit, which is connected or connectable to the inverter. The shielding is connected capacitively to a ground of the inverter, and a pulsed voltage is generated on the conductor by the inverter. The measuring device is designed to evaluate a voltage between the ground of the inverter and the shielding and to generate a short circuit signal when at least one pulse of the voltage occurs.
