Current-limited Power Supply Model

 

Ever wanted to make a power supply that was current limited? Here is an easy way to generate a current-limited voltage source.
Current-Limited Supply
The source is implemented with an NTIOFV source. This source has its voltage controlled by the current flowing through its input terminals according to a tabular list. You control the degree of current limiting by constructing the appropriate current, voltage data pairs in the table. Here is a plot of the output voltage versus the input current. Notice that it exactly matches the values specified in the TABLE attribute.
