Additional Losses of Inverter Fed Asynchronous Induction Machines of Traction Drives – Comparison of Modelling and Measurements
نویسندگان
چکیده
Additional losses of asynchronous induction machines utilized in traction drives caused by the inverter have a great impact of the thermal behaviour of such machines. Therefore, an accurate modelling and evaluation of these additional losses is a very important task in particular with the initial design. Based on detailed measurement data from already built machines, a fast and reliable calculation method of these additional losses suitable for the initial design of new machines is presented based on equivalent circuits of the induction machine for each higher harmonic components of the terminal voltages applied by the inverter.

The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...
