Abstract
An electronic circuit for starting a single phase induction motor, of the type containing a rotor and a stator with at least one running coil (B) and one starting coil (B), for operating jointly with an alternating current source (F), comprising: a trigger electronic switch; a trigger circuit (TR) of said trigger electronic switch; and a blocking circuit (BL) for controlling the trigger pulses of the trigger electronic switch, said blocking circuit (BL) sustaining its blocking state while there is voltage being induced to the coils of the motor (M) by rotation of the rotor, maintaining said blocking state for a certain time after said induced voltage has been substantially reduced.
