Abstract

Niskonaponski trofazni izmjenjivač je uređaj učinske elektronike koji služi za pogon trofaznih motora različitih vrsta. U radu je ukratko opisan način rada BLDC motora te pojava reverznog vođenja poredne diode. Blokovski su opisani podsustavi niskonaponskog izmjenjivača te njihova uloga u radu izmjenjivača, što uključuje: pobudni stupanj, upravljačka jedinica, sustav za mjerenje struja faza i sustav za obradu signala s Hall sondi. Na temelju dokumentacije proizvođača poluvodičkih komponenata određeni su gubitci vođenja i sklapanja MOSFET-a i poredne diode. Dobiveni su rezultati koji pokazuju gubitke MOSFET-a i gubitke diode. Na kraju, izrađen je i prijedlog nacrta tiskane pločice u KiCAD programu za izradu tiskanih pločica.

Abstract (english)

Low-voltage three phase inverter is a power electronics device used for driving various types of three phase motors. In this paper, the principal of operation of BLDC motor and phenomenon of reverse conduction of freewheeling diode were briefly examined. The subsystems of the low-voltage inverter and their role in the operation of the inverter were described in blocks, which includes: driving stage, control unit, current measuring system, Hall signal measurement system. Based on the documentation of the semiconductor component manufacturer, the conduction losses and switching losses of both MOSFET and freewheeling diode were calculated. Finally, printed circuit board design was proposed using KiCAD.
