circuitsolver_6

As I neared my senior year for my B.S. in Electrical Engineering, I wanted to created
something that most people hadn’t done before. 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.

circuitsolver_1Circuit Solver is far from perfect and there are lots of things that could be optimized. It will however, solve a majority of linear Circuits and a decent amount of smaller scale Non-Linear Circuits.

DC Analysis:
To solve 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.

circuitsolver_2Transient Analysis:
In transient analysis 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 Analysis:
Non linear analysis is used for components such as diodes, LEDs, and transistors. 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.
