Abstract:Namen diplomskega dela je bil razvoj sistema za napajanje industrijskih senzorjev na osnovi digitalno nastavljivega in baterijsko napajanega enosmernega pretvornika kot nadgradnja brezžičnega komunikacijskega modula, ki zagotavlja nastavljivo napajalno napetost za različne industrijske senzorje. Pretvorba baterijske napetosti na nastavljivo izhodno napetost je bila narejena s stikalnim pretvornikom navzgor, kateremu je bil v povratno vezavo priključen digitalni potenciometer. Za nastavljanje upornosti digitalnega potenciometra (in s tem izhodne napetosti) je bil uporabljen mikrokrmilnik. Izdelana je bila Windows aplikacija, s pomočjo katere je možno preko Bluetooth povezave komunicirati z brezžičnim modulom. Iz rezultatov opravljenih meritev je bilo zaključeno, da realiziran pretvornik navzgor v večji meri ustreza predpisanim karakteristikam v projektnih zahtevah. Na koncu so bile podane morebitne izboljšave in nadgradnje izdelanega sistema.

Title:POWER SUPPLY SYSTEM FOR INDUSTRIAL SENSORS
Abstract:The aim of this thesis was to develop a power supply system for industrial sensors based on digital adjustable and battery powered DC/DC converter. The system was designed as an upgrade of wireless communication module which provides adjustable voltage for various industrial sensors. The conversion of battery voltage to an adjustable output voltage was made with boost converter and a digital potentiometer in the converters's feedback loop. For adjusting the resistance of the digital potentiometer (and thus the output voltage) a microcontroller was used. A windows application was developed with the help of which it is possible to communicate with wireless module via Bluetooth connection. From the results of the performed measurements, it was concluded that the realized boost converter largely corresponds with the project specifications. In the end, possible improvements and upgrades were given.
Keywords:embedded system, boost converter, digital potentiometer, Bluetooth
