Abstract:
A capacitor energy store charging system comprising:a. a capacitor energy store load to be charged to a pre-determined voltage level;b. a single-phase alternating current (AC) power source;c. an AC switching means capable of turning the AC power source on and off on command;d. a high-reactance transformer means driven by the AC power source whereby the maximum short circuit current that can load the power source is determined and which provides a voltage step-up or step-down to accommodate the required voltage level on the capacitor energy store;e. a rectifier means whereby the output of the high-reactance transformer is converted into direct current to charge the capacitor energy store; andf. a controller means capable of accepting external input commands, sensing the phase of the AC power source, sensing the voltage of the capacitor energy store, and commanding the AC switching means.
