Programmable ring-type switched-capacitor dc-dc converters
Autor: Takahiro Inoue, Fumio Ueno, Ikko Harada, Noriaki Hara, Ichirou Oota
Publikováno v: Electronics and Communications in Japan (Part II: Electronics). 82:14-27
New dc–dc converters are presented whose step-up and step-down ratio can be controlled easily by changing their external clocks. These converters consist of switched capacitors that form a ring connected by MOSFET switches (“ring-type SC”). The

Power supply for electroluminescent lamp employing a switched-capacitor AC-AC converter
Autor: Ikko Harada, Fumio Ueno, Ichirou Oota, Takahiro Inoue
Publikováno v: Electronics and Communications in Japan (Part II: Electronics). 78:90-100
A new ac-ac converter using switched-capacitor (SC) transformers is presented. The proposed converter is shown to be useful for electroluminescent lamps (EL). The proposed converter has a novel configuration of ac-ac conversion characterized by the p

Power supply for electroluminescence aiming integrated circuit
Autor: Takahiro Inoue, Ichirou Oota, Ikko Harada, Fumio Ueno
Publikováno v: [Proceedings] 1992 IEEE International Symposium on Circuits and Systems.
For promoting the application of electroluminescent (EL) devices, a thin-plate-typ DC-AC converter is required. For this purpose, a novel type of power supply that uses switched capacitor (SC) transformers is presented. This power supply generates on

Emergency power supply for small computer systems
Autor: Ikko Harada, Fumio Ueno, Takahiro Inoue, Ichirou Oota
Publikováno v: 1991., IEEE International Sympoisum on Circuits and Systems.
A small size emergency power supply was investigated. This was realized by adopting a quick detector of momentary power failure and a compact DC-DC converter. The power failure detector has a novel type of T-V (time-voltage) conversion using an SC (s
