摘要:
According to the configuration and the manufacturing method of forming a moisture proof agent on both surfaces of a circuit substrate after soldering a capacitor connection pin in a vertical direction to the circuit substrate, and electrically connecting the capacitor so as to be in a perpendicular direction to the length direction of the capacitor connection pin at the upper space of the circuit substrate, the possibility of the moisture proof agent attaching to the capacitor is eliminated, the productivity enhances since the moisture proof agent can be easily formed on both surfaces of the circuit substrate, and a capacitor unit of miniaturized and low height configuration is realized since the capacitor is mounted in the horizontal direction in the upper space with respect to the circuit substrate.

The vehicle power supply apparatus includes a main power supply (11), a load (15) connected to the main power supply (11), an electric storage unit (31) that stores the electric power from the main power supply (11), and a control circuit (43) that controls the electric storage unit (31) to supply electric power from the electric storage unit (31) to the load (15) when the voltage (Vb) of the main power supply (11) becomes smaller than a predetermined threshold value. The control circuit (43) inhibits supplying of the electric power from the electric storage unit (31) to the load (15) in a vehicle nonuse state when the electric power is supplied from the main power supply (11) to a starter (23) to start the engine of the vehicle, and when any electric power is not supplied from the main power supply (11) to the load (15).
摘要:
A power supply device is used for an apparatus which includes a power generator and a parallel assembly including a main power supply and a load. The power supply device includes a input port connected to an output terminal of the power generator, an output port connected to the parallel assembly, an electric storage element charged with electric power generated by the power generator, a switching unit, a current switcher for restricting a current flowing from the main power supply to the electric storage element, a controller for controlling the power generator such that the voltage of the output port becomes a predetermined voltage. The switching unit is connected to the first input port, the output port, and the electric storage element. The switching unit connects the electric storage element, the power generator, and the parallel assembly in parallel to each other when the electric storage element is charged with the electric power generated by the power generator. The switching unit connects the electric storage element, the power generator, and the parallel assembly in series to each other when the electric storage element is discharged to supply electric power stored in the electric storage element to the parallel assembly. This power supply device can provide an apparatus including only one power generator with a regenerating function.
