A CONTROL CIRCUIT

摘要

A control circuit ( 101 ) is configured for use with a load in the form of hardware ( 102 ) of a laptop computer ( 103 ). Circuit ( 101 ) includes input terminals ( 105, 106 ) for electrically connecting with respective terminals ( 107, 108 ) of a battery pack ( 109 ). The battery pack ( 109 ) supplies a battery current and has a predetermined maximum operational current. Circuit ( 101 ) also includes output terminals ( 111, 112 ) for electrically connecting in parallel hardware ( 102 ) and a supercapacitor ( 113 ). A controller ( 115 ) is disposed between the input and the output terminals for allowing the battery to transfer energy to hardware ( 102 ) and supercapacitor ( 113 ) while maintaining the battery current at less than the predetermined maximum operational current.
