Implementation And Validation Of A New Strategy Of Online Practical Works Of Power Electronics For Embedded Systems
INTERNATIONAL JOURNAL OF ONLINE ENGINEERING(2017)
摘要
This paper presents the implementation and validation of a Remote laboratory for Practical Works (PWs) of power electronics for embedded systems. This work falls within the framework of an international project between several universities of the Maghreb and Europe. The aim is to create a Remote Practical Laboratory of 3rd year Bachelor degree in Electronics and Optics e-Learning for Embedded Systems (EOLES). This paper presents the topologies and architectures description of various realized practical manipulations and developed software/hardware platforms. The presented results relate to 3 PWs of the power electronics. The first two practical works (WP1 and WP2) are respectively, "Uncontrolled simple phase half and full wave rectifiers", While the PW3 deals the study of a Buck-converter connected on various loads. The results are presented and discussed according to two levels. The first is a comparison of the results of electronic measurements with the theory. The second deals with comparison of this Remote system with the same PW performed by the classical method "in-class". Based on an analysis of the students Quality Assessment of these PWs, the results show the limits of validity and reveal the strengths and weaknesses of this new educational strategy in the University pedagogical system, and the possibility of its used in other types of training and disciplines.
