英文摘要 | The Metacapacitors project aims to improve efficiency, functionality and form factor of offline power converters suitable for LED solid-state lighting, with a view to developing an attractive technology platform for load management and power conversion across a broad range of applications. Based on integrated switched-capacitor (SC) topologies, the project adopts an integrated approach from materials to devices to circuits. We designed capacitors based on high-κ dielectric nanocrystals, that can be prepared using high-throughput microfabrication/ nanotechnology techniques, ink deposition and multilayering. The capacitor dielectric, a nanocomposite composed of (Ba, Sr)TiO3nanocrystals in polyfurfuryl alcohol (BST/PFA, κ > 20, 100Hz-1 MHz, loss 1000 h at 125°C. The capacitors were board integrated with a custom hybrid-switched-capacitor-resonant dc-dc converter IC. The converter integrates a balanced SC front-end with a series resonant tank, enabling nearly lossless current regulation and tranformerless galvanic isolation. The converter IC can be stacked in the voltage domain to interface a range of inputs. The tested driver delivers about 15 Wat 470 mA to a string of 12 LEDs with 90% peak efficiency. © 2015 IEEE. |
