kretssimulering

Kretssimulering, or circuit simulation, is the process of using computer programs to model the behavior of electrical circuits. These simulators analyze how a circuit will function under various conditions, predicting voltage, current, and power levels at different points. This allows engineers and hobbyists to design, test, and troubleshoot circuits without the need for physical prototypes, saving time and resources.

There are various types of circuit simulators, each suited for different applications. DC analysis determines the steady-state DC behavior of a circuit, while AC analysis examines its response to alternating currents. Transient analysis simulates how a circuit behaves over time when subjected to changing inputs or initial conditions. More advanced simulators can also model non-linear components, thermal effects, and electromagnetic interference.

Commonly used circuit simulation software includes SPICE (Simulation Program with Integrated Circuit Emphasis) and its numerous derivatives like LTspice, PSpice, and ngspice. These tools are fundamental in the design and verification of integrated circuits, printed circuit boards, and various electronic systems. By identifying potential issues early in the design phase, circuit simulation significantly reduces the risk of costly errors and design flaws.
