Simulation of diode operation and evaluation of its operation parameters

Abstract

The article discusses the simulation of the operation of a diode based on the compiled electrical circuit, and also considers the analysis of the operation of the dido under various operating conditions using the AnyDynamics 8 computer simulation program. Various approaches to the concept of modeling, model, and mathematical model are considered. The classification of models of semiconductor devices, current-voltage characteristic (CVC) and device operation scheme are evaluated. The physical properties of the diode are considered, then a transition is made to the analysis of the operation of the diode in a physical model, and on its basis a mathematical model of the diode is built, since the model works with small changes in current and voltage, then the transition is made to a low-signal model and a system of differential equations, behavior of an ideal diode. Classes of elementary elements are being developed, from which it is possible to build an electronic circuit, diode, resistor, capacitor, coil. A circuit is determined with the help of which it is possible to simulate the operation of a circuit with a connected ideal diode. The result of the work of the electrical circuit in the program AnyDynamics 8 was the creation o behavior of an ideal diode. Analysis of the obtained graphs in the future will allow you to perform modeling and analysis of the operation of an ideal diode.
