ASYNCHRONOUS AC CONVERTER-FED MOTOR Russian patent published in 2011 - IPC H02K29/03 H02K17/02 H02P27/00 

FIELD: electricity.

SUBSTANCE: asynchronous ac converter-fed motor with supply from DC source comprises an m-phase winding with even quantity of phases installed on a stator. All phase windings are arranged with a middle lead connected to one terminal of the supply source. End leads of n winding are connected to the second terminal of the supply source by means of controlled key elements, where n = 1, 3, 5, etc., at the same time end leads of (n + 1) winding are connected to the specified leads of n winding via diodes connected in accord relative to current in according sections of n winding. There is a capacitor connected in parallel to each section of (n + 1) winding.

EFFECT: simplified design by simplification of a circuit of an asynchronous motor connection to a DC source, increased reliability of this motor by reduction in quantity of switching key elements.
