LTspice: Behavioral Voltage Sources

Simon Bramble - Field Applications Engineer Apr 4th 2016

Nearly all circuits that you simulate need a voltage source of some kind. In LTspice, the humble voltage source rarely gets to demonstrate its true capabilities. This video will help you learn some of the undiscovered talents of the LTspice voltage source. In this video we’ll explore the power of the behavioural voltage source and see what mathematical functions LTspice can bring you to further stimulate your circuit. A behavioural voltage source outputs a voltage according to any number of circuit parameters and it can be used to unleash the real mathematical power of LTspice.

 

 


Software

LTspice

LTspice® software is a powerful, fast and free simulation tool, schematic capture and waveform viewer with enhancements and models for improving the simulation of switching regulators. Click here to download LTspice

To launch a ready to run LTspice demonstration circuit for this part:

  • Step 1: If you have not installed LTspice on this computer, download and install LTspice
  • Step 2: Once LTspice is installed, click on the link(s) below to launch the simulation
  • Step 3: If LTspice does not automatically open after clicking the link above, you can instead run the simulation by right clicking on the link and selecting "Save Target As." After saving the file to your computer, start LTspice and open the demonstration circuit by selecting 'Open' from the 'File' menu
