DC Voltage Source block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simscape / Electrical / Additional Components / SPICE Sources

Description

The DC Voltage Source block represents a constant voltage source whose output voltage value is independent of the current through the source.

Examples

SPICE Conversion of a CMOS Voltage Comparator

A typical implementation of a CMOS voltage comparator and how you can convert a SPICE subcircuit to a Simscape™ component using the subcircuit2ssc function. You can use CMOS voltage comparators in analog to digital converter (ADC) or relaxation oscillator circuits.
