Research on Fault Simulation of Electronic Circuit

This paper takes the adjustable DC power supply circuit as an example to discusse a method for fault simulation of electronic circuits based on Multisim. By using the fault setting function of Multisim 14.0, and setting the circuit to different types of faults, simulates the real fault phenomenon and display the results with virtual instruments. The fault simulation is useful for understanding the working principle of electronic circuit, predicting the fault cause and selecting device parameters in circuit design.
