Intelligent type opening multifunctional power electronic experimental device

Abstract

The invention relates to an intelligent type opening multifunctional power electronic experimental device which comprises a power source, a module assembly, a display screen and a switch. A touch screen is adopted in the display screen which is provided with a plurality of functional buttons, different circuits can be selected according to requirements, and the different module functions can be achieved. The module assembly is provided with a plurality of functional modules including a direct current chopping circuit module, a phase-controlled rectification circuit module and a sine pulse width modulation inverter circuit module, each functional module corresponds to a corresponding printed circuit board, and each printed circuit board comprises an electronic element and a signal terminal. Circuits are conveniently expanded and connected, and different measuring meters and loads are connected into the circuits from the exterior. The power source is a three-phase four-line alternating current power source, is connected into the circuits through an isolation transformer and a voltage regulator, and is converted into different-stage alternating current and direct current power sources needed by various modules through an auxiliary power source inside the device. The intelligent type opening multifunctional power electronic experimental device is reasonable in design, convenient to operate, simple in structure, strong in intuition sense and capable of helping students or researchers to master the basic experimental method and strengthen basic skill training.

AI Technical Summary

Problems solved by technology

After researching the device, the applicant found that there are only a few circuits that can provide experiments, and these circuits have a single structure and low performance

The problem is that the LED display unit is too simple

Its shortcoming is that the realization of virtual experiments through network management makes users lack the sense of immersive practical operation

Moreover, there is still a certain deficiency in the training for improving the user's practical operation skills.

This device is not conducive to the improvement of students' hands-on ability required in the practical training, and is not conducive to students' intuitive familiarity and practicality of the functions of electronic devices.
