ABSTRACT:
A high efficiency automotive electrical system and method of control employing an asynchronous induction machine for performing both starting and generating functions. The induction machine is coupled to the engine through a bimodal gearset which operates as a reduction drive during the starting mode and as a direct drive during the generating mode. A computer-based controller responsive to the battery voltage and the speed of the induction machine maintains given voltage/frequency ratios during both starting and generating to provide efficient operation, and smoothly controls the transition between starting and generating modes. The vehicle electrical loads are supplied at one or more stable voltages produced by a load converter powered by the battery.
