A connector includes: a first connector terminal to which a first electric cable is to be connected; a second connector terminal to which a second electric cable is to be connected; a sidewall that surrounds the first connector terminal and the second connector terminal; a protection cover; and an interlock mechanism. The interlock mechanism includes an interlock connector and an interlock pin. The interlock connector is disposed between the first connector terminal and the second connector terminal, and the interlock pin is provided at the protection cover and is positioned such that the interlock pin is inserted into the interlock connector when the protection cover is attached to the sidewall.

A boost converter capable of reducing a common-mode current that flows to the outside of a casing. In the converter, a boost circuit includes first and second inductors and at least one switching element electrically connected therebetween. A controller turns on and off the at least one switching element to boost an input voltage of the boost circuit. A first floating capacitor is formed between a first electrical path, which is at the same potential as a junction between the at least one switching element and the first inductor, and a mounting member coupled to a reference potential member with an insulator therebetween. A second floating capacitor is formed between a second electrical path, which is at the same potential as a junction between the at least one switching element and the second inductor, and the mounting member.

A power supply apparatus for a vehicle supplies/charges electric power to/from a power supply unit. The vehicle includes a first power-inverter circuit, a capacitor, high-resistance and low-resistance electric-paths between the capacitor and a battery, a first switching unit opening/closing the electric-paths, and a unit operating the first switching unit, when connecting between the battery and the first power-inverter circuit, in such a manner that after the high-resistance electric path is closed and the low-resistance electric path is opened, the high-resistance electric-path is opened and the low-resistance electric-path is closed. The apparatus includes an electric power transferring electric-path, an operating unit operating the first power-inverter circuit to supply/receive electric power to/from the power supply unit, and a prohibiting unit prohibiting the electric-path between the power supply unit and the first power-inverter circuit from closing when the amount of charge of the capacitor is equal to or less than a predetermined value.

Power supply apparatus for vehicle

A power supply apparatus for a vehicle is provided which supplies electric power to a power supply unit and charges electric power from the power supply unit via a power port. The vehicle includes a plurality of power inverter circuits which are connected to a common storage unit in parallel. The plurality of power inverter circuits include an electric power transferring power inverter circuit connected to the power port via an electric power transferring electric path, and are divided into a first category including the electric power transferring power inverter circuit and a second category. The power supply apparatus includes a connection prohibiting unit which realizes a state in which the power inverter circuit included in the first category is electrically connected to the storage unit, and the power inverter circuit included in the second category is disconnected from the storage unit.

An inverter device for changing direct current to alternating current for supplying to an electric motor which may be employed in an electric automobile. This inverter device includes a plurality of switching units, a cooling support member, capacitors, and pairs of first and second conductive plates. Each of the switching units has a box-like casing mounted on the cooling support member, and includes a positive switching element, a negative switching element connected in series, and positive and negative terminals. The positive and negative terminals are exposed on the upper wall of the casing. Each of the capacitors is arranged over an upper wall of the casing of a corresponding one of the switching units, and has positive and negative charge/discharge terminals. The first conductive plate of each pair connects the positive terminal of one of the switching units with the positive charge/discharge terminal of a corresponding one of the capacitors, while the second conductive plate of each pair connects the negative terminal of one of the switching units with the negative charge/discharge terminal of a corresponding one of the capacitors.
