Practical Exploration For Guiding Simulation Into Experimental Course Of Circuit Analy

The "Circuit Analysis" is the important basic course for electronic information specialty. In this course, the experiment section of circuit analysis is good for students to strengthen the students’ professional knowledge, and to understand theories deeply, and to improve their practices and creativity, especially assigning some theoretical calculation. With the development of computer information technology, it have become an important way to using simulation software to conduct test. The advantages of simulation experiment are following: it can simplify processes and improve efficiency. It makes the test safer by instead of dangerous or difficult actual operation. It can remedy the lack of components and extend the spaces and contents of experiments to develop tests with designing, exploratory and research.This paper studies how to use the Multisim simulation software conducting simulation experiments in traditional physical circuit experiment.At present, the circuit experiments are mainly practicality experiment, which the group numbers are according to the sets of equipments and limit more students to take parting in the experiments. But with simulation experiments, more students have chance to practice and master the knowledge and do much more tests.The practicality experiment can strengthen the operating ability, but with many objective limits, which limit the teacher to inspect the circuits and test the correctness of data, because in practicality experiment, same circuit and same factor lead to same result. Although in comprehensive designing experiment, there will be results as long as designing the circuits, but the results cannot be verified. However, these problems all can be solved.In verification test of DC circuit, the simulation experiment can make each student with different factor. Especially testing Thevenin’s Theorem, it will not afraid the results are influenced giving rise to instrument internal resistance as do in practicality experiment. And the simulation experiment can design different instrument internal resistance to study how the internal resistance influences the results.In single phase AC electric circuit experiment, the simulation experiments obtain the data soon, and leave out complex calculation by using the exchange and analysis function of software, and the curve also can be consistence with theory.In three-phase circuit experiment, the simulation experiments can set loading value, for example, the loading value is zero.After two terms practices of using simulation experiments in circuit experiments, it obtain good value from course teachers and students. So, the simulation experiments achieve the desired objects.
