摘要

In this paper, a novel approach has been employed in order to investigate the efficient design of a vector control drive of a high speed PMSM for automotive application using analytical method and real time simulator. Most of vector control drives set the d-axis current to zero to decrease the magnitude of the source current and working with unit power factor. However, the optimal d-axis current is dependent to the motor specifications. An optimal estimation scheme has been proposed and tested in order to work with maximum efficiency based on the operation point. In the high speed application, because of high losses density and low capacity of heat dissipation, the importance of working in maximum efficiency point will be clear more and more. Also, measurement of inverter losses is very complicate in the analytical approach. In this paper, the precise model of the switches has been implemented using real time simulator. Real time simulator, is a complex electronic circuit which is composed of CPUs, FPGA, etc.-s known as an efficient tool obtains very exact model of the IGBTs in order to have the precise losses model of the motor and drive. Both of the analytical approach and real time simulator prove the validity of the optimal estimation scheme.
