Method, circuit adaptor and adaptor to control a bridge inverter with a multiple nu00ecveis controller of induction motor with two nu00ecveis and.The drive system of induction motor to drive a three phase motor.This is a method and a circuit that allows the controllers to off the shelf intended for use with a bridge inverter drive of alternating current to drive bridges D (1920)And the inverter with three or more levels.The signals of a controller of induction motor controller or a common induction motor with two levels (2200) are used to trigger 12 or more switches of a bridge inverter t.Three or more levels (1920), such as are used in medium and high voltage applications.The sequ00b3u00eancia appropriate and the timing of switching to the bridge inverter three or more levels are based on a part at the exit of the modulators of six wrists or at the output of the deviceControl of flux and torque control device, or the voltage (2210), the controller of two levels (2200).
