FIELD: electrical engineering.
SUBSTANCE: proposed converter consists of two AC machines with magnetic circuits on stators and rotors and windings of armatures and inductors with input and output terminals, and control and adjustment unit. Machines rotors are fitted on common shaft. First machine has additional magnetic circuits on stator and rotor made up of separate laminated circular stacks. AC toroidal windings are arranged between adjacent circular stacks. Armature winding of the first machine is arranged on the rotor and connected with rotor winding of additional magnetic circuit, while inductor winding of the first machine is designed for alternating currenta and made on stator and connected to the output terminal of second machine armature winding via control and adjustment unit. The latter represents a static frequency converter. Note also that input terminals are arranged on toroidal winding of the stator.
EFFECT: simplified design.
