Abstract
A primary power source in the form of a direct energy converter provides d.c. voltage to a d.c. to a.c. converter. This in turn provides energy to an a.c. motor. The motor with appropriate speed control drives a mechanical load. When the energy of the primary source is depleted, an auxiliary engine is automatically started. The engine drives a d.c. generator which now supplies energy to the d.c. to a.c. converter. In addition, the d.c. generator can recharge the primary source. The primary power source may also be charged by an external power source. A computer controls the elements or components of the system.
