Résumé :	The steady state analysis of the conventional static Kramer drive using three different types of models, namely the DC, AC and DQ models is developed in the first part of the thesis. The aim is to arrive at a correct prediction of the basic steady state characteristics of the drive through correlation of results of the different models used. This is motivated by the fact that most of the published work done on stability analysis of this drive relied on a wrong DQ steady state model. A correct DQ steady state model is established. The stability analysis of the static Kramer drive is presented in the second part of the thesis. A set of nonlinear differential equations describing the dynamic and steady state behaviour of the system are developed and linearized about an operating point using small signal perturbation technique. The eigenvalues loci of the system are plotted for different operating points with the effects of system parameter changes on the drive stability investigated for three such drives of different power levels. In support of analytical predictions, transient responses to a load torque step change have been obtained by solving the set of non linear equations representing the actual system. Conclusions reached in this present investigation study show important differences with previous research work. It has been found that both the operating point and the power level of the drive are important factors influencing the drive stability.
