Abstract
An improved power supply system involves load-leveling the large transient currents drawn by a high power, low duty-cycle load application circuit by means of a high performance capacitive charge storage device, such as a super-capacitor or a network of super-capacitors. The improved power supply system allows the high power load application circuit to be driven by a limited energy power source, such as a battery or the power supplied to a PCMCIA slot by a host computer. When the input voltage source is a battery, the improved power supply system allows for a substantial increase in the battery's operational life. The inventive system is particularly useful for managing power supply requirements for miniaturized wireless transmission systems, such as two-way pagers or radio modems, which employ low duty-cycle packet-switched RF transmitters.
