Abstract

Ovaj rad opisuje izradu sustava otporničke opteretne mreže varijabilne snage i pripadajućeg sustava aktivnog hlađenja za primjenu u DC mreži. U prvom dijelu napisan je uvodni dio rada. U drugom dijelu opisane su ukratko osnove energetske elektronike, kao i neki od elektroničkih komponenti korištenih u radu. U trećem je dijelu prikazana elektronička shema otporničkog sustava, određeni su toplinski parametri te je prikazan matematički model zagrijavanja otpornika. Matematički model napravljen je na osnovi snimljenih promjena temperature otpornika u vremenu, a prijelazna karakteristika zagrijavanja opisana je PT1Tt članom. U četvrtom dijelu prikazan je elektronički sklop aktivnog hlađenja, dok se u posljednjem dijelu nalazi Arduino kod u kojem su objedinjene funkcije za upravljanje otpornicima, kao i PI regulacija temperature.

Abstract (english)

This paper describes the development of a variable power resistive load network system and
the associated active cooling system for use in a DC network. The first part contains an
introduction to the paper. The second part briefly describes the basics of power electronics, as
well as some of the electronic components used in the paper. In the third part, the electronic
scheme of the resistor system is presented, the thermal parameters are determined and the
mathematical model of the resistor heating is shown. The mathematical model was made on the
basis of recorded changes in resistor temperature over time, and the transient heating
characteristic is described by the PT1Tt term. The fourth part shows the electronic active
cooling circuit, while the last part contains the Arduino code, which combines the functions for
controlling resistors, as well as PI temperature control.
