In recent years the simulation tools have been optimized for precise modelling and simulation for their special purpose. Therefore the simulation tools have been developed to model and simulate a certain problem. In the past, the hardware was used to be modeled in a SPICE simulator, the software in a signal and differential equation based simulator. Nowadays the investigated systems are decreasingly...
This paper presents a few examples of the possibility of effective use of open-source simulation tools within the project gsim to solve the problems of the electronics in educational and professional practice. The fundamental difference with regard to commercial products are open file and data formats, the possibility of creating own components and macro models. An essential advantage is the easy...
This article presents the development and implementation of a model for a silicon carbide PiN diode based on the physics of the semiconductor. The main novelty in this paper is modelling with Pspice the real stored charge inside SiC PiN diodes depending on the working regime of the device (turn-on, on-state, and turn-off). By means of this methodology a set of differential equations that models the...
A free SPICE version allowing general circuit simulation is used teaching power electronics. There is no lock on the circuit size, stabile and user friendly operation is experienced. A collection of transformer, converter and drive system models are implemented to investigate the usability of the programme in high power electronics.
The paper deals with the problem of modelling d.c. characteristics of silicon power Schottky diodes with thermal effects taken into account. The electrothermal model of the investigated diodes was formulated for SPICE and experimentally verified. The evaluation of accuracy of the elaborated model has been performed by comparison of measured and calculated characteristics of a selected Schottky diode.
Many electronic circuits and systems operating at low voltages are battery-powered. As a linear voltage regulator is used to this end, it has to be characterized by a high power efficiency, which can be achieved by a low voltage drop (LDO) across a pass element. In this paper a d.c. model of the voltage regulator LDO REG 104-5 V is presented. The theoretical considerations are illustrated by the results...
