Description

The DC Voltage Source block implements an ideal DC voltage source. The positive terminal is represented by a plus sign on one port. You can modify the voltage at any time during the simulation.

Ports

Conserving

+ — DC voltage source positive terminal

specialized electrical

Specialized electrical conserving port associated with the DC voltage source positive terminal.

- — DC voltage source negative terminal

specialized electrical

Specialized electrical conserving port associated with the DC voltage source negative terminal.

Parameters

To edit block parameters interactively, use the Property Inspector. From the Simulink^® Toolstrip, on the Simulation tab, in the Prepare gallery, select Property Inspector.

Amplitude — Source amplitude

100 (default) | nonnegative scalar

Amplitude of the source, in volts (V).

Measurements — Measurements option

None (default) | Voltage

Select Voltage to measure the voltage across the terminals of the DC Voltage Source block.

Place a Multimeter block in your model to display the selected measurements during the simulation. In the Available Measurements list box of the Multimeter block, the measurement is identified by a label followed by the block name:
