With the development of power electronics devices, resonant converter is proved to be more efficient than conventional converter as it employs soft switching technique. Among the three basic configuration of resonant converter, Series Resonant Converter (SRC), Parallel Resonant Converter (PRC) and Series Parallel Resonant Converter (SPRC), the LLC configuration under SPRC is proved to be most e...

This paper presents a method for designing the control loop for dc-to-dc converters when uncertainties exist in the ac characteristics of the converter’s load. In the proposed method, a converter is initially considered as a stand-alone module feeding a current sink load and the control loop of the converter is then designed in a way that maximizes the robustness of the converter’s closed-loop ...

This study presents the proposal for calculations of overall characteristics of unit HC emissions from passenger vehicles. Inspiration for the project was derived from the author’s own research and the research works by the selected centres, both in Poland and abroad. Overall, (static) characteristics, with maps of unit emissions of HC, CO and NOx were employed as a basis. This assumption is ba...

In this paper we demonstrate the potential of combining electric hybridization with a dual-fuel natural gas-Diesel engine. We show that carbon dioxide emissions can be reduced to 43 gram per kilometer with a subcompact car on the New European Driving Cycle (NEDC). The vehicle is operated in charge-sustaining mode, which means that all energy is provided by the fuel. The result is obtained by ha...
