Abstract: Switching devices control the rectification and flow of alternating current power from a source such as an alternator to a load such as a battery in response to both the voltage of the battery and a minimum selected time period that is selected to eliminate or reduce an imbalance between various phases or polarities in possible current carrying paths. The selected time period may be constant or a predetermined function of variables such as the speed of the alternator.

Abstract: This disclosure relates to a pulse generator for triggering successive energy discharges such as in automotive or other ignition systems and the like, which generator comprises a magnetic circuit a portion of which is interrupted by a conductive vane the position of which controls the production of the pulses and at least one winding encircling a portion of said magnetic circuit, means connecting said winding to the output of an amplifying means, said components connected to produce as negative feedback at the input of said amplifying means the total voltage across said winding; the magnetic circuit and electronic circuitry connected thereto being so arranged as to minimize the number of components which must be placed in close physical proximity to the rotating vane, generally in the distributor of the engine, and to also minimize the number of interconnecting leads from the vane location to the balance of the ignition system, thus producing a small, inexpensive and highly accurate pulse generator.
