| dc.title | A novel interleaved current-source switched-inductor step-up converter with interleaved current-source boost filter | en_US |
| dcterms.abstract | Switched-inductor (SL) converter family is not a new technology, but most research has been focused on voltage-source (VS). The current-source (CS) converter family has been proposed in recent years and has attracted much attention. The main issues with CSSL converters include high voltage stress on components and high distortion in the output waveforms. For most VS converters, this issue can be solved through multi-phase interleaving, but it is not so easy for CSSL converters, especially current step-up converters with inductors as the only energy storage components. | en_US |
| dcterms.abstract | This dissertation provides a brief introduction to the conventional VSSL converter family, followed by an analysis of operation principles for three basic types among this converter family. Then, a novel interleaved topology of step-up CSSL converters, derived from an existing CSSL step-up converter, has been proposed in this dissertation. To further improve the output current waveform, an interleaved CS current step-down filter is proposed, which is based on a similar structure previously exclusive to three-level VS Boost converters and voltage balancing. Simulations of each topology are done in Simulink, and a hardware prototype cascading two interleaved converters is constructed and verified. An open-loop control circuit is also designed. | en_US |
| dcterms.abstract | The investigation of interleaved CSSL step-up converters may provide some extra consideration for designing SL converters. The study of interleaving methods should also further deepen the understanding of CS converters, which have not been discussed as much as VS converter families. | en_US |
