The alternative power system provides microprocessor grade, filtered output power capable of replacing standard NiCad battery packs in portable electronic devices. The invention makes use of capacitor banks comprised of capacitors having different values, whereby the individual capacitors act as individual filters to substantially eliminate all transients which are present in the source of power, which is typically provided by rechargeable batteries on a host system, such as a forklift or hand truck.

[ I claim:] [1.] A highly regulated power supply which is particularly adapted for converting "dirty" power available from a storage battery on a host vehicle to highly regulated, "clean" power suitable for powering portable electronic devices, comprising:(a) a pair of input terminals for receiving power from said storage battery;(b) a first circuit for smoothing out said power received from said storage battery;(c) a dc-to-dc converter, which receives, as its input the power from said first circuit;(d) a first capacitor bank, used to pass transients ground, said first capacitor bank being connected to the output of said dc-to-dc converter through a diode;(e) a voltage regulator connected across the terminals of said first capacitor bank, the output of said voltage regulator being used to accurately adjust the output voltage of said dc-to-dc converter though a trim control on said dc-to-dc converter; and(f) a second capacitor bank, connected to the output of said dc-to-dc converter and across the output terminals of said power supply, said second capacitor bank also being used to pass transients which are in the output of said dc-to-dc converter, to ground, whereby only highly filtered power is provided to the output terminals of the power supply for use by external devices.
