Capacitor - less Buck
Low-power switched-mode power supply converters are used in applications where size and efficiency are critical. The buck converter size can be reduced by elimination of the bulky filter capacitor. The filtering function of this capacitor can be replaced by an output current ripple compensation circuit. The compensating circuit is applied, based on inductor current measurement and linear amplif...
متن کاملIntroduction to the Series Capacitor Buck Converter (Rev. A)
The series capacitor buck converter is a dc-dc converter topology that uniquely merges a switched capacitor circuit and a multiphase buck converter. Many of the challenges faced by conventional buck converters are overcome by this converter topology. This enables efficient, high frequency operation and significantly smaller solution size. The series capacitor buck converter has beneficial chara...

متن کاملIntegrated Buck-Buck-Boost AC/DC Converter
Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...
متن کاملLinearization of Cascaded Buck Converter
The present work deals with the modeling and the stability analysis of the cascaded converters. When a converter tightly regulates its output, it behaves as a constant power load (CPL). The problem of CPLs is that they show negative incremental resistance that causes instability in the system because the control to output transfer function possessed a RHP pole. Hence the CPL has been modeled an...
