Electronically adjustable active load for support of laboratory work – feasibility of an implementation
Němec, Pavel ; Hruboš, Zdeněk (referee) ; Šotner, Roman (advisor)
This master’s thesis deals with active electronic loads focusing mostly on alternating input signals. The principles and modes of both DC and AC loads are described, as well as the most important parameters of MOSFET transistor which is used as the main power component. It deals with designing a regulation circuit of an AC load in detail. This work also discusses the possibilities of realisation of the remaining parts of the device. At the end of the thesis the function of the designed regulation circuit is verified by simple measurements on a prototype.

Verification of Mathematical Model for Small Power Sources
Vrána, M.
This paper describes a method of verifying the mathematical model of the power supply. Simple equations describing the specific energy source. As an example photovoltaic panel was chosen. Simultaneously, there are described equation for calculating the solar radiation incident on the optionally oriented surface. These equations are used to model and convert the radiation which is recorded by meteorological stations. Reference panel and load are used for model validation. The goal of this paper is to describe a model of energy sources and its validation.
