This paper presents a concept and experimental results of the magnetic-less converter suitable for wide temperature range operation. The DC-DC converter uses a variant of a switched-capacitor voltage multiplier topology, silicon carbide (SiC) and IGBT (insulated gate bipolar transistor) semiconductors and resonant circuits with air-based chokes designed on PCB (printed circuit board), as well as high temperature resonant capacitors and PCB materials. Ferrite materials are not required which and therefore the problems with inductance variation versus temperature do not exist.

PL

W artykule przedstawiono koncepcję i wyniki doświadczalne przekształtnika do pracy w szerokim zakresie temperatur. W przekształtniku zastosowano wariant topologii rezonansowo przełączalnych kondensatorów, półprzewodniki z węglika krzemu (SiC) i IGBT oraz obwody rezonansowe z dławikami powietrznymi zaprojektowanymi na PCB, a także wysokotemperaturowe kondensatory rezonansowe oraz specjalny materiał PCB. Rdzeń ferrytowy nie został tu zastosowany, a zatem nie istnieje problemy ze zmianą indukcyjności w zależności od temperatury pracy układu.
