摘要
经典的DC/DC变换器,如Buck变换器、Boost变换器、Buck-Boost变换器、罗氏变换器和Cuk变换器,通常都是由电感和电容组成,所以它们的体积大而功率密度低。开关电感已被成功地应用于DC/DC变换器中,开创了设计高功率密度变换器的方法。如美国麻省理工学院(MIT)的John G.Kasskian教授为下一世纪未来的汽车设计了一种新的电源系统,该系统的核心就是一个在+42V和+14V直流之间进行变换的二象限DC/DC变换器。
Classical DC/DC converters usually consist of inductors and capacitors such as buck converter, boost converter, buck - boost converter, Luo - Converter and Cuk - Converter[1-5] . Because all classical converters consist of ca-pacitors and inductors, they have big size and low power density. Switched inductor has been successfully em-ployed in DC/DC converters and opened the way to build the converters with high power density. For example, Professor John G. Kassakian of MIT designed a new power supply system for the future car in next century [6]. The heart of this system is a Two - Quadrant DC/DC Converter operating the conversion between + 42V and +14 VDC.
