A power supply () for powering a load, the load being in the form of a flash driver circuit () for a digital camera (not shown). The power supply includes a supercapacitive device, in the form of a supercapacitor (), for powering circuit (). A regulator unit, in the form of an inductive regulator (), charges supercapacitor ().

Power supply that uses a supercapacitive device

A power supply () for a load in the form of a PCMCIA card () has and onboard GPRS class (10) module (not shown). The module, and therefore card (), demands a load current ithat has an average value over time and periodic instantaneous peak values (i) that are significantly higher than the average value. Power supply () includes a pair of input terminals () for connecting with a power source in the form of a regulated power supply () that is contained within a personal computer (not shown). Supply () supplies a source current ithat is less than a predetermines current limit specified for the supply and which is less than the peak load current. A pair of output terminals () is electrically connected with terminals () and card (). A supercapacitor device in the form of a single supercapacitor () is in parallel with terminals () for allowing the load to be supplied the peak load current while maintaining the source current at less than the predetermined current limit.

Power supply

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