    Abstract: A slip recovery system for a wound rotor induction motor is disclosed in which first and second inverters, connected in series, are coupled to the rotor of the induction motor. A switch is arranged in parallel with the second of these inverters, the switch being in the open position during starting and stopping of the motor, and being closed to short out the second inverter during normal running conditions. Thus, the first inverter need have only a voltage rating of such magnitude so as to satisfy the expected operating range for the wound rotor, while the second inverter need have only a voltage rating of sufficient magnitude to satisfy the additional capacity requirements for stopping and starting service. Thus, lower rated inverter components may be used with lower initial costs as well as concomitant lower operating costs.
