摘要： A system and method (referred to as a method) to fabricate sensors and electronic circuits. The method prints a first thin-film having an electronic conductivity of about less than a millionth of a Siemens per meter and a permalloy directly onto the first thin-film. The permalloy has a magnetic permeability greater than a predetermined level and has a thickness within a range of about 1 to 20 microns. The system prints a second thin-film directly onto the permalloy to encapsulate the permalloy onto the first thin-film and prints conductive traces directly onto the surfaces of the first-thin-film, the permalloy, and the second thin-film. In some applications, a sensor is packaged in an additively manufactured three-dimensional cylindrical shape that can be mounted on or is a unitary part of a current carrying conductor without incising, sharing, or severing (e.g., cutting) the current carrying conductor or its insulation.

摘要： A shunt resistor having sufficient bonding strength includes a resistor, a pair of bases which are integrally formed with the resistor so as to sandwich the resistor, recessed holes which are respectively formed in the bases, and measurement terminals which are inserted into the recessed holes and are affixed to the bases. Each measurement terminal has a shaft part and a flange part that protrudes outwardly in the circumferential direction of the shaft part. Each recessed hole is formed to have a diameter smaller than the diameter of the flange part, and the shaft parts are respectively inserted into the recessed holes.

摘要： A switching circuit comprising a transistor and a drive component both for controlling the transistor and also for limiting the power supply current supplied to a load, the drive component being arranged both to receive a control voltage and also: when the control voltage is a disconnection signal, to generate a drive voltage that causes the transistor to occupy a non-conductive state; when the control voltage is a connection signal and the power supply current cannot reach a predefined current threshold, to generate a drive voltage that causes the transistor to occupy saturated conditions; and when the control voltage is a connection signal and the power supply current can reach a predefined current threshold, to generate a drive voltage that causes the transistor to occupy linear conditions, such that the power supply current is regulated so that it does not exceed the predefined current threshold.
