根据AN112 Step-Down DCDC Converter Input Ripple and Noise(文件地址https://u.dianyuan.com/upload/space/2010/12/06/1291639764-378686.pdf)和AVNET Input Capacitor Considerations(找不到原文地址了,给出截图),输入电容ESR纹波电压分量应该是D*Iout*ESR。 所以,以上5种形式的输入电容ESR纹波电压分量哪个才是...
buck convertermodel-based controlThis paper presents the modeling and control of a DC-DC buck converter with reduced output ripple which is achieved without additional switching devices. The converter results from replacing the LC output network in a conventional buck converter for an LCL network ...

Fig.1 SIDO Buck converterSIDO Buck变换器的开关管占空比存在Di>Db、Di=Db和Di<Db三种情况,对应有三种工作方式[12],由于三种工作方式的分析方法类似,限于篇幅,本文以Di<Db的工作方式为例对SIDO Buck变换器的供能模式和输出纹波电压进行讨论。1.1 CCM供能模式分析当SIDO Buck变换器工作在CCM时,根据最小电感电流IL...
In a multiphase buck converter running at precise duty cycles which have an inverse integer relationship with the number of phases and a precise synchronized phase relationship, it is possible to have zero output ripple. If the output inductors are replaced with coupled inductors having nominally the...
A constant frequency output-ripple-voltage based CMOS current-mode dc-dc buck converter, providing fast load transient response and reference-tracking speed, is proposed in this paper. Unlike V2 control output-ripple-voltage based buck converter, the proposed buck converter can achieve fast and stabl...
Measuring output voltage ripple can be a quick way to evaluate the performance of modern power converters and low dropout (LDO) devices. Different measurement methods may lead to the opposite evaluation results of the output ripple. How to obtain accurate ripple values becomes the most important ...
In order to increase the voltage gain of the Buck-Boost converter and reduce the output current ripple, the method of topology combination is adopted, and ... 李梦娇,彭继慎,孙瑄瑨 - Journal of Liaoning Technical University (Natural Science Edition) / Liaoning Gongcheng Jishu Daxue Xuebao (Ziran...
To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter).[1] Fig. 1: Buck converter circuit diagram. 3 A buck converter Switching converters (such as ...
relationships between the pulse combination and the output voltage ripple. By using the dynamical analysis method, the discrete time model of current-mode DPSM DCM buck converter is established, and the combination laws of high power control pulse, low power control pulse and skipped control pulse...
