Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Switched Battery DC–DC Converters for Low-Power Applications

“…Despite a limited power-capability of the battery in comparison to existing SCC using flying capacitor, the SBC offers an undeniable advantage. Indeed, a key difference between these two architectures is that SCC experiences a natural tradeoff between its inherent charge-sharing losses and switching losses at low power levels [24]. Following equation gives the condition to meet in the case of 2:1 SCC:…”

Analytical Benchmarking of Direct Hybrid Switched-Capacitor DC-DC Converters

“…In such cases, the passive components, typically capacitors and inductors, often dominate the size of the converter. To reduce the volume of these passive components, recent efforts have focused on increasing the switching frequency [1], using resonant topologies [2], introducing inductorless piezoelectric structures [3]- [5], using alternative flying components [6], [7], and high density Silicon capacitor components [8], [9]. Among all of these solutions, hybrid switched-capacitor converters (HSCCs) are considered amongst the most promising [10], [11] and have received significant attention over the last decade.…”
