Application number: 17/417,627

Abstract:
An electric wire with a terminal described herein includes a shielded electric wire 11 and an inner conductive member 20. The shielded electric wire 11 includes a covered wire 12 including a core wire 13 through which a signal for communication is transmitted and an insulation cover 14 that has insulation property and covers the core wire 13, a shielding portion 15 having electric conductive property and covering an outer periphery of the covered wire 12, and a sheath 16 covering an outer periphery of the shielding portion 15. The inner conductive member 20 is connected to the covered wire 12. The covered wire 12 has an end portion close to the inner conductive member 20 and the end portion is an uncovered portion 17 that is not covered with the sheath 16 and the shielding portion 15. The uncovered portion 17 is covered with an impedance adjustment member 80 that has electric conductive property.

Application number: 17/430,556

Abstract:
An on-board power supply device includes: a voltage conversion unit; a first voltage detection unit that detects a value of a first voltage that is applied to a second conduction path; and a second voltage detection unit that detects a value of a second voltage that is applied to a load-side conduction path. Furthermore, the on-board power supply device includes: a target voltage setting unit that sets a target voltage value based on the value of the second voltage detected by the second voltage detection unit; and a control unit. The control unit repeatedly performs feedback calculation for updating a duty ratio of a control signal based on the value of the first voltage detected by the first voltage detection unit so as to bring the value of the first voltage applied to the second conduction path closer to the target voltage value.
