Abstract:
An electrical power system for powering an electronic device, comprising:a power source configured to provide a first output voltage, and;a rechargeable battery communicating with said power source, said rechargeable battery configured to provide a second output voltage, said second output voltage being higher than said first output voltage;said power system having a voltage multiplier circuit interconnected between said power source and said rechargeable battery, said voltage multiplier circuit having an input, an output and a plurality of charging capacitors interconnected between said input and said output, said voltage multiplier circuit configured to electrically interconnect said plurality of charging capacitors in parallel when said first output voltage is present at said input, and further configured to electrically interconnect said plurality of charging capacitors in series when said first output voltage at said input is approximately zero, said voltage multiplier circuit configured such that said first output voltage across said plurality of charging capacitors is added and provided as boosted voltage at said output, said boosted voltage being provided to said rechargeable battery to recharge said rechargeable battery.
