Application of the electrothermal average inductor model for analyses of boost converters

Abstract: This paper describes the boost converter analyses using electrothermal average models. The form of electrothermal average models of the diode — transistor switch and the inductor dedicated for SPICE is shown. The usefulness of the presented models to calculate the characteristics of the boost converters is shown on the example of a boost converter containing the inductor with the ferrite core. The obtained results of computations of the electrothermal average model are compared with the results of measurements and computations made by the selected literature models.

Modelling and the Analysis of the Power Supply System for the Generator of Hydrogen

Abstract: In the paper the manner of characterising properties of the generator of hydrogen and the form of the computer model of this generator are presented. The model was formulated in the form of a subcircuit for SPICE software. The structure of this model is described and the values of parameters of the model are presented. With the use of the proposed model some dc and frequency characteristics of the considered generator are calculated and compared to the measured characteristics. Some results of analyses of the considered generator operating in different supply conditions are presented and discussed.
