<p>Apparatus for converting dc electrical power to ac electrical power, comprising dc winding means and ac winding means, each winding means including a plurality of turns and being fixed in relation to one another; a ring of high permeability material encircling the winding means, in closely-spaced relationship, and switching means for selectively connecting dc electrical power to separate turns of the dc winding means in a prescribed sequence, to produce a magnetic flux pattern that rotates around the fixed position dc winding in a predetermined fashion thereby to induce an ac electrical power signal in the ac winding means.</p> |
