Abstract:V diplomskem delu je predstavljen dvosmerni stikalni DC/DC pretvornik, ki se uporablja za dvosmerni prenos energije v sklopu elektromotornega pogona v hibridnih ali električnih vozilih. Pretvornik lahko deluje v načinu navzdol (Buck), kadar s presežno energijo pri zaviranju ali vožnji navzdol polnimo hranilnik energije, ali pa v načinu navzgor (Boost), kjer z akumulirano energijo v hranilniku poganjamo elektromotor. S simulacijo delovanja je bila preverjena in potrjena izbrana topologija pretvornika, rezultati simulacije pa so nam tudi pomagali pri načrtovanju in izbiri komponent, kjer smo največ pozornosti namenili načrtovanju močnostne dušilke. Izmerjen je tudi izkoristek pretvornika v obeh načinih delovanja.
Keywords:stikalni DC/DC pretvornik, hibridna vozila, električna vozila, močnostna dušilka, pulznoširinska modulacija, simulacije, vodenje, meritev izkoristka

Title:BI-DIRECTIONAL DC/DC CONVERTER
Abstract:This work presents bidirectional DC/DC converter, which is used for a bidirectional energy flow in the hybrid or electric vehicles. The converter has two main operating modes - step-down mode (Buck) and step-up mode (Boost). When operating in Buck mode, the converter uses an excess energy from breaking or driving downhill to charge an energy storage device. In contrary, when the converter works in Boost mode, the accumulated energy is transferred from energy device to the electric motor. Before the converter was implemented, the simulations were executed. The simulation results gave us useful information based on which the converter's components were selected. A special attention was devoted to the design of the power inductor. Also the efficiency of converter was measured.
Keywords:switching DC/DC converter, hybrid vehicles, electric vehicles, power inductor, pulse width modulation, simulations, control, efficiency measurement
