Dynamic Cross Platform Circuit Simulation Platform.

Project description


Circuit Solver is developed to make sure it’s capable of generating correct simulation results should the user understand that it’s a fixed timestep solver. PhasorSystems is not liable for any incorrect simulation results.

NOTE: This is only tested w/ file version 1.1.9 and above. There is no gurantee that it will work for older files.

This engine will allow you to run the simulation engine for circuit solver without a user interface. It will also allow you to edit parameters when the simulation is running and in turn do dynamic simulations such as battery models, buck or boost converters, etc.

Tested On:

Python 3.8.5


Note: The demo requires numpy and pandas to work correctly.

pip install mnapy

To get the test files nagivate to:

Download “ACSourceInitial_nl.txt” and “”

Change the FILE_LOCATION in to match where ever your “ACSourceInitial_nl.txt” is located. Run If everything goes well a window should open up with a waveform that should look like an acsource.

Generating New Files:

In order to load new files into the system, go to or use the desktop version (windows only atm). Build your circuit and in order to port this to the headless version press: CTRL + P. This will generate a {FILE_NAME}_nl.txt file that can be loaded into this headless engine.

Note: Set_Switch_State(setter: str) and Set_Interpolate(setter: str) can be set by:

Set_Switch_State(engine.Params.SystemConstants.ON) or Set_Switch_State(engine.Params.SystemConstants.OFF)

if (Get_Switch_State() == engine.Params.SystemConstants.ON) or if (Get_Switch_State() == engine.Params.SystemConstants.OFF)

The same thing applies for Interpolate.
