TRIGGER DEVICE Russian patent published in 2011 - IPC H02P1/46 H02P25/02 H02K19/08 

FIELD: electricity.

SUBSTANCE: trigger device comprises capacitor joined serially with one of phases of electric motor, transformer, primary winding of which is connected to network via switching element. Secondary winding of transformer is connected serially with the second phase of electric motor. Number of turns in the primary and secondary windings of transformer is selected based on and number of turns in phases of electric motor is same.

EFFECT: improved power properties and starting torque of electric motor, reduced capacitance of capacitor.
