Power electronic digital-analog hybrid system for technical skill training

Abstract

The invention discloses a power electronic digital-analog hybrid system for technical skill training. The power electronic digital-analog hybrid system comprises a low-voltage physical model control system and a low-voltage physical model, wherein the low-voltage physical model control system is connected and communicated with the low-voltage physical model, and the low-voltage physical model is communicated with a digital simulation platform through an interface transfer plate and a photoelectric conversion plate. The power electronic digital-analog hybrid system has the advantages that the performance such as electrical characteristics, control protection strategies and equivalent parameters of a practical device can be vividly demonstrated by the low-voltage physical model, in addition, the operation parameters can be automatically set, and the control strategies can be changed, training students can contact real electric devices and personally carry out operation before the mount guard, theory and practice are combined, the theory learning is enhanced, and in addition, the hand-on operation capability is trained. The digital simulation platform in the system can be used for digital simulation study, and can be communicated with the low-voltage physical model control system, so the low-voltage physical model is controlled, and the on-line real-time simulation is realized.

AI Technical Summary

Problems solved by technology

At present, in the field of power electronics experiment teaching, there is no real power electronics device for students to demonstrate and operate, so that students will not be deeply impressed, the relevant knowledge is not firmly grasped, and the theoretical knowledge learned cannot be well applied to practice

In addition, existing digital simulation systems for power electronics can only perform simple simulations, and cannot perform online real-time communication simulations with power electronics devices.
