ABSTRACT: This paper investigates the use of a dual stator winding squirrel-cage induction machine for generating dc power using series- or parallel-connected ac-dc pulse width modulation rectifiers. The operating principles and constraints when generating under minimum total copper-loss condition are explored using the machine steady-state model considering magnetizing flux saturation effects. Regulation of the dc voltage using concepts of the nonlinear input-output linearization method including the design of the controllers is set forth and confirmed to be effective by computer simulation results. Some experimental waveforms of the generator under load are also included in this paper

ABSTRACT: This paper presents a control methodology for the dc voltage regulation of an induction generator/ac-dc boost rectifier system, in which the copper loss of the generator is minimized. With the aid of an input-output linearization technique, which linearizes and decouples the model equations in the synchronous reference frame, a rotor-flux-vector-control-type high performance is achieved. Steady-state analysis provides some insights into the operability regime of the generator. The effectiveness of the control scheme under different load conditions as well as varying rotor speeds has been demonstrated by computer simulations. Some experimental results have been included
