Implement a DC voltage source

Library

Electrical Sources

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.

Dialog Box and Parameters

Amplitude

The amplitude of the source, in volts (V).

Measurements

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:

Measurement	Label
Voltage	Usrc:

Example

The power_dcvoltage demo illustrates the simulation of the transient response of a first-order RC circuit.
