Abstract[English]
The present disclosure proposes a family of ultra-high step-up DC-DC converters for photovoltaic (PV) systems, fuel cells, switched-mode power supplies, etc. The suggested layouts are made by combining a buck-boost-based input stage with voltage multiplier (VM) cells and coupled-inductors (CI) cells. The VM network of each topology contains an arbitrary number of cells to increase the voltage gain. The proposed topologies are categorized based on the number of their magnetizing components in single-inductor (SI) and dual-inductor (DI) converters. The second inductor of DI converters increases the voltage gain without the need for extreme duty cycles, high coupling ratios, or adding more VM cells.[French]
La présente divulgation concerne une famille de convertisseurs CC-CC à élévation ultra-élevée pour des systèmes photovoltaïques (PV), des piles à combustible, des alimentations électriques en mode commuté, etc. Les agencements suggérés sont fabriqués par combinaison d'un étage d'entrée Buck-Boost avec des cellules de multiplicateurs de tension (VM) et des cellules d'inducteurs couplés (CI). Le réseau VM de chaque topologie contient un nombre arbitraire de cellules pour augmenter le gain de tension. Les topologies proposées sont catégorisées sur la base du nombre de leurs composants de magnétisation en convertisseurs à inducteur unique (SI) et à double inducteur (DI). La seconde bobine d'induction de convertisseurs DI augmente le gain de tension sans nécessiter de cycles de service extrêmes, de rapports de couplage élevés ou d'ajout de davantage de cellules VM.
