An electrically conductive path is configured from a first copper plate, a second copper plate, and solder. The first copper plate has a first bent section extended from a first joining section joined to an electrically insulative board and bent toward the rear surface of the electrically insulative board. The second copper plate has a second bent section which is extended from a second joining section joined to the electrically insulative board, is bent toward the front surface of the electrically insulative board, and is disposed so as to cover, together with the first bent section, the inner wall surface of a base-material through-hole. Through-holes are provided in the portions of the second copper plate which face the inside of the base-material through-hole. Solder is filled between the first bent section and the second bent section.

Wiring board and method for manufacturing wiring board

A power control device for a vehicle includes a first battery, a second battery, the voltage of which is lower than the voltage of the first battery, and a transformer. The transformer includes a primary coil, to which an alternating-current power source is connected, a first secondary coil, to which the first battery is connected, and at least one second secondary coil, to which the second battery is connected. A rectification circuit is located between the second secondary coil and the second battery. A voltage adjustment circuit is located between the rectification circuit and the second battery. A control section charges the first battery using the alternating current power source, and, simultaneously supplies electrical power to the second battery.

Power source device

A hybrid vehicle includes a power generator that generates electric power using power from an internal combustion engine; a motor that outputs power for travel of the hybrid vehicle; a first inverter connected to an electric power storage device and the motor to drive the motor; a second inverter connected to the electric power storage device; and a large drive power determination portion that determines whether the hybrid vehicle is in a large-drive-power required state in which drive power equal to or larger than a predetermined value is required for the travel of the hybrid vehicle. When it is determined that the hybrid vehicle is not in the large-drive-force required state, the second inverter is connected to the power generator. When it is determined that the hybrid vehicle is in the large-drive-force required state, the second inverter is connected to the motor.

Hybrid vehicle and method of controlling hybrid vehicle

A power converter that can be used in a vehicle equipped with an electrical motor provides power to both the electrical motor and other, auxiliary loads, such as a headlamp, that require a different voltage. The power converter includes a first DC power supply that generates a first voltage equivalent to the voltage required by the auxiliary loads and a second DC power supply, connected in series with the first DC power supply, that generates a differential voltage, where the sum of the differential voltage and the first voltage is the voltage required to drive the electrical motor. A DC-DC converter is connected to the second power supply and converts the differential voltage to the voltage required to drive the auxiliary loads.
