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.
Claims4
A rotary inverter comprising the combination of a rotary field winding, a stationary armature winding including two separate winding portions which are electrically isolated from one another but magnetically coupled together, switching means for controlling the connection of a d.c. supply to tappings on one armature winding portion in synchronism with the rotation of the field winding, and a.c. output terminals connected to the other armature winding portion.
