SHARED HYBRID VIRTUAL-EXPERIMENTAL LABORATORY FOR TRAINING IN POWER ELECTRONICS TECHNIQUES

摘要

This paper analyzes the possibility of using a new philosophy of experimental engineering laboratory for power electronic converters applied to electric machine control. The aim is to develop an environment which, on the one hand, permits the students to design hardware and software blocks that can be incorporated into an electronic power system and, on the other hand, allows the communication and control of this system via the web. The students work in groups, on asynchronous and synchronous software platforms, on the same task and they should look for the best solution for the required design. The drawbacks related to high voltages and currents, waiting for attention from the professor, the high cost of maintenance and updating of an experimental laboratory can be overcome with the use of the Shared Hybrid Virtual-Experimental Laboratory (SHVEL). The validation of the proposed method has been carried out on an experimental system based on the digital signal processor DSP56F807 and on the free software platform FreeMaster from the commercial firm Freescale?.
