Abstract
An apparatus generates sine waves of electromotive force (i.e. alternating current) from a battery. The battery includes a given number of cells connected in series. A stator and commutator is formed by a multiple of segments. Each of the segments is connected in sequence to a respective cell of the battery. The apparatus can be incorporated in a rotary switching device that further includes a rotor having at least one brush contacting the segments of the stator and commutator to carry a step waveform approximating a sine wave. The rotary switch can be included in various setups to provide a backup or alternate generator that provides alternating current.
Claims16
An apparatus for generating sine waves of electromotive force, comprising:
- a battery including a given number of cells connected in series;
- a stator and commutator formed by a multiple of segments, the multiple equaling said given number of cells multiplied by a natural number;
- each of said segments being connected sequentially to a respective one of said cells.
A rotary switch, comprising:
- a battery including a given number of cells connected in series;
- a plurality of stators and commutators each formed by a multiple of segments, said multiple equaling said given number of cells multiplied by a natural number, each of said segments being connected sequentially to a respective one of said cells, and said stators and commutators being connected in parallel to said battery;
- and
- a respective rotor for each of said stators and commutators, each having a brush and turning concentrically within said commutator with said brush contacting said segments.
