High-Ratio Voltage Conversion in CMOS for Efficient Mains-Connected Standby [Paperback]

This book describes synergetic innovation opportunities offered by combining the field of power conversion with the field of integrated circuit (IC) design. The authors demonstrate how integrating circuits enables increased operation frequency, which can be exploited in power converters to reduce drastically the size of the discrete passive components. The authors introduce multiple power converter circuits, which are very compact as result of their high level of integration. First, the limits of high-power-density low-voltage monolithic switched-capacitor DC-DC conversion are investigated to enable on-chip power granularization.  AC-DC conversion from the mains to a low voltage DC is discussed, enabling an efficient and compact, lower-power auxiliary power supply to take over the power delivery during the standby mode of mains-connected appliances, allowing the main power converter of these devices to be shut down fully.   

Introduction.-Switched-capacitor DC-DC in bulk CMOS for on-chip power granularization.- Toward monolithic integration of mains interfaces.- A single-stage monolithic mains interface in 0.35 ?m CMOS.- Two-stage approach for compact and efficient low power from the mains.- An 11/1 switched-capacitor DC-DC converter for low power from the mains.- Monolithic SC DC-DC towards even higher voltage conversion ratios.- Conclusions and future work.

Hans Meyvaert was born in Sint-Truiden, Belgium, in 1985. In 2009 he received the degree of M.S. in Electrical Engineering from the Katholieke Universiteit Leuven, Belgium. The subject of his MS thesis was on the design of a fully-integrated 130nm CMOS high power switched capacitor voltage down converter. He is currently working as a research assistant at the MICAS laboratories of the Katholieke Universiteit Leuven towards a PhD degree in the field of high temperature electronics.
