Meyvaert H., Steyaert M. High-Ratio Voltage Conversion in CMOS for Efficient Mains-Connected Standby

Springer International Publishing, 2016. — XIV, 151 p. — (Analog Circuits and Signal Processing). — ISBN: 978-3-319-31207-1, 978-3-319-31206-4.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.Standby Energy Consumption.
