Abstract
A high frequency inductive emf circuit charges storage capacitors, one at a time, from a DC source to a voltage that is higher than the DC output voltage. After each storage capacitor is charged, it is disconnected from the charging circuit and then connected to an output device/regulator that uses the energy in each storage capacitor to provide the desired DC output voltage to a load. While one storage capacitor is being charged, a previously charged storage capacitor is being discharged through an output device/regulator. After being discharged, each storage capacitor is disconnected from its output device/regulator and reconnected to the charging circuit and is charged again. While being charged, the storage capacitors are in a parallel circuit to the inductor in the charging circuit. The inductor in the charging circuit and the DC source are never in a current loop with the load.
