The description of Circuit Solver
As I approached my senior year for my B.S. in Electrical Engineering, I wanted to create
something that most people hadn't created before, a circuit simulator! It was about the experience, the learning, and the the journey itself. I put together this application to package my knowledge in
Electrical Engineering to some day help another student have an easier time in their
scholastic pursuits and in turn teach them about circuits. Circuit Solver is far from perfect and there are lots of things that could be optimized. It will however, simulate a majority of linear Circuits and a decent
amount of smaller scale Non-Linear Circuits. If this app helps you in any way, i'd appreciate you spreading the word to help support my efforts, Thanks!
To simulate the circuits, a matrix is defined based on all the components inside the circuit. The application solves the circuit using matrix manipulations such as LU-Decomposition and matrix inversion. DC Analysis is completed by writing a series of nodal equations. The equations are solved simultaneously to obtain a unique solution.
In transient simulation we use numerical integration to determine the response of RLC circuits. Numerical integration allows for one to solve for discrete moments of time and in effect integrate their response. This application only supports the Trapezoidal method.
Non Linear Simulation:
Non linear simulation is used for components such as diodes and LEDs. The solver first guesses the approximate value of the solution and is refined through the use of a Newton-Raphson process. It utilizes linear approximation to predict the answer through successive iterations.
Visualize waveforms through the use of the built in oscilloscope. To use this feature simply link either a volt meter or an amp meter to the graph by tapping on them and pressing the eye, in order to view the wave.
Save your circuits on your device to use anywhere you go and at any time. You may also capture screen shots of the circuits you build. These screen shots are saved locally on your device.
