  • Open Circuit block

Description

The Open Circuit block represents an electrical terminal that draws no current.

You can use this block to terminate electrical ports on other blocks that you want to leave open circuit. This is not necessary because if you leave a conserving port unconnected, the physical network sets all the Through variables at that port to 0. However, terminator blocks improve diagram readability.

You can also use this block to set the initial absolute voltage at a node.

Variables

To set the priority and initial target values for the block variables prior to simulation, use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector). For more information, see Set Priority and Initial Target for Block Variables.

Model Examples

Operating Point RLC Transient Response

Operating Point RLC Transient Response

The response of a DC power supply connected to a series RLC load. The goal is to plot the output voltage response when a load is suddenly attached to the fully powered-up supply. This is done using a Simscape operating point.
