Abstract

U završnom radu analizirani su uzroci nastanku jalove snage. Objašnjene su formule koje opisuju ovisnost faktora snage o nelinearnosti trošila i izobličenju napona. Predstavljena je važnost stabilnog iznosa faktora snage. Navedene su razlike pasivnih i aktivnih načina korekcije faktora snage. Predstavljena su četiri metode pasivne korekcije faktora snage, te su objašnjene razlike između njih. Aktivni način korekcije faktora snage ostvaruju se upotrebom komponenata i uređaja učinske elektronike. U radu su predstavljeni jedno-stupanjski i dvo-stupanjski pretvarač za korekciju faktora snage, te su opisane razlike između njih.

Abstract (english)

In this work is analyzed the reasons for the formation of reactive power. The paper explains the different formulas for power factor depending on the nonlinearity of load and voltage distortion. Paper presents importance of stable power factor. Differences between passive and active mode power factor correction are pointed. Paper presents four ways passive power factor correction, and the provided difference between them. Active mode of correction consists of various circuits and power electronics circuits, and the paper presented single-stage regulator and a two-stage regulator for power factor correction, and are given the differences between them. With the development of power electronics will result in an improvement of the power factor correction and thus optimizing the power factor.
