| Abstract |
The paper deals with an actual induction motor used in high energy consumption applications. Different inverter configurations driving the same machine are considered, and theoretical tools for comparison of such configurations are established, essentially based on efficiency evaluations. Two different methods, an equivalent circuit analysis and a direct modeling technique are proposed in order to deduce the effective inverter voltage or current outputs feeding the motor. The motor and the overall system efficiencies are then evaluated, taking into account all motor and inverter losses. Experimental tests are also presented, showing validation of the cormputer predicted results. |
