Apparatus and method for initial charging, self-starting, and operation of a power supply with an intermittent and/or variable energy source and a rechargeable energy storage device

摘要

A power supply for supplying energy to a load includes an energy supply source for generating energy, an energy storage device that is charged from the energy generated by the energy supply source, an optional regulator for improving the energy matching of the energy supply source and the energy storage device, an energy converter for delivering energy from the energy storage device and/or the energy supply source to a load, a detector for monitoring the energy level of the energy storage device and for determining when to activate the energy converter to allow energy delivery to the load from the energy storage device and/or the energy supply source, an optional energy discharge controller that allows the energy storage device to discharge over time, and an optional switch controller for controlling a switch, valve, relay, etc.
