ABSTRACT:
An electrical storage device comprises a capacitor or capacitor bank capable of storing significant quantities of electricity. An inverter in circuit with the capacitor converts direct energy of the capacitor into alternating current. A variable ratio transformer is in circuit with the output of the inverter to produce an alternating current output of controlled voltage. The impedance of the transformer acts to prolong discharge of the capacitor over a significant time period. To further control the rate of discharge of the energy storage capacitor, an additional capacitor may be provided in the transformer circuit.
