Abstract
A rotary inverter for converting d.c. to a.c. includes a rotary field winding and a stationary armature including two windings. One winding is supplied with d.c. switched in synchronism with the rotation of the field winding. The other winding is electrically isolated from the first mentioned winding but is magnetically coupled thereto and provides the a.c. output. The two windings occupy the same slots in the armature.
