A power supply control system including a variable power converter for converting electric power from a power supply to a load into that of a specification required by the load in response to a power specification information source provided on the load side. With a change in the load, the information source also changes, thereby providing a flexible power supply control system capable of meeting different loads. For applications to a high power supply, the system comprises a plurality of variable power converters adapted to operate selectively in accordance with requisite power information sources provided in or on the side of a plurality of loads, thereby providing a system realizing a flexible power supply. For application to a low power supply, the system comprises a plug having a power specification information source and a socket having a variable power converter.
A socket with a power conversion function interposed between a power supply and a load for transmitting electric power from the power supply to the load, said socket comprising means for converting the power from the power supply into a power of a given specification, means for controlling the conversion means in such a manner that the output of the conversion means may be of a specification required by the load, and means for supplying the output of the conversion means to the load, and further comprising memory means for storing a plurality of specifications required by the load and switch means for selecting a specification stored in the memory means as the specification required by the load.
A socket with a power conversion function, comprising:
A socket with a power conversion function comprising:
A socket for interposition between a power supply and a load provided with terminal means, the socket enabling transmission via the terminal means of electric power from the power supply to the load, the socket comprising:
A socket for interposition between a power supply and a load provided with terminal means, the socket enabling transmission via the terminal means of electric power from the power supply to the load, the socket comprising:
A plug for connection to a socket, the plug having a function of transmitting information to the socket, the plug and the socket being for interposition between a load and a power supply, wherein the plug comprises signal output means for transmitting to the socket a specification of electric power required by the load, first power receiving means for receiving power from the socket to drive the signal output means, and second power receiving means for receiving power from the socket to drive the load.
A socket for interposition between a power supply and a load, the load including terminal means for receiving electric power and at least two signal output terminals for outputting an electric signal representative of a specification of electric power required by the load, the socket enabling electric power from the power supply to be supplied to the load, the socket comprising:
A socket for interposition between a power supply supplying an AC voltage and a load, the load including terminal means for receiving electric power and specification output means for outputting a specification of electric power required by the load, the socket enabling electric power from the power supply to be supplied to the load, the socket comprising:
A socket for interposition between a power supply supplying an AC voltage and a load requiring AC electric power, the load including terminal means for receiving electric power and specification output means for outputting a specification of AC electric power required by the load, the socket enabling electric power from the power supply to be supplied to the load, the socket comprising:
A plug for connection to a socket, the plug and the socket being for interposition between a load and a power supply, the plug comprising:
A plug for connection to a socket, the plug and the socket being for interposition between a load and a power supply, the plug comprising:
A plug for connection to a socket, the plug comprising:
