Abstract:Za projekt je bila izdelana zasnova modernizacije vezja polnilnika svinčenih baterij, ki se uporablja v talni akumulatorski lokomotivi Schalke GaE-08 v Premogovniku Velenje. Delo se je začelo z analizo in meritvami na obstoječem polnilniku. Na podlagi pregleda alternativnih topologij je bila izbrana struktura usmernika Vienna v kombinaciji z DC-DC pretvornikom navzdol. Delovanje predlaganega močnostnega vezja ter podporne elektronike je bilo preverjeno in optimizirano s pomočjo simulacij. Preračunane so bile zahteve hlajenja polprevodnikov. Izdelani so bili načrti tiskanih vezij ter celotne električne povezave sistema, pri čemer so bili upoštevani varnostni elementi. Obravnavan je bil tudi teoretični potek programa za vodenje polnilnika.

Title:Modernization of the charging circuit for the Schalke floor-mounted battery locomotive
Abstract:As part of the project, a design for modernizing a lead-acid battery charger used in a floor-mounted battery locomotive, the Schalke GaE-08, at the Velenje Coal Mine, was developed. The work began with an analysis and measurements of the existing charger. Based on a review of alternative converter topologies, a structure combining a Vienna rectifier with a step-down DC-DC converter was selected. The operation of the proposed power circuit and the associated auxiliary electronics was verified and optimized using simulations. The cooling requirements of the power semiconductors were calculated. Printed circuit board layouts and the complete electrical interconnection of the system were designed, with safety elements considered. The theoretical control algorithm of the charger was also addressed.
Keywords:Vienna rectifier, Buck converter, Power electronics
