Batteries current ripples in float charge mode

2017 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2017
In this article, the research of battery chargers in boost charge mode is performed using a mathematical model in EMTP-RV program. During research the root-mean-square value of current ripples were defined while different types of batteries supplying.

Wilton ripples phenomenon with a background current

The Physics of Fluids, 1985
The Wilton ripples phenomenon with a background current is examined in detail. The case of most interest occurs when the current is near the threshold value such that direct resonance occurs for the Wilton ripples. Interaction between the fundamental mode and its second harmonic occurs on a much faster time scale.

Double Pulse Modulation on Current Ripple Suppression

Advanced Materials Research, 2014
In the process of the DC-DC conversion, suppressing the output current ripple is very important. Compared with conventional single pulse modulation mode ,double-pulse modulation can more effectively suppress the output current ripple. By principle analysis, the formula is derived, and finally through simulation proved double pulse modulation can ...

Comparison of the Peak-to-Peak Current Ripple

2014
This chapter gives the overview on all the developed cases, and proceeds with the comparison within different cases. First presented is the comparison of the output current ripple between cases with different phase numbers, i.e. three-, five-, and seven-phase inverters.

Influence of Direct Current Ripple on Metal Deposition

Circuit World, 1991
This paper focuses on the quality of output current rectification—an important feature which should be taken into account alongside voltage and current. It is the author's intention to provide other authors and equipment manufacturers with the incentive to elaborate on this theme.

Control of current ripple in dc-dc converters

2009
An investigation is conducted into the analysis of power converters from the ripple point of view. In short, the thesis is about a deep understanding of the basic dc-dc converter from the ripple viewpoint and thus develops a family of converters with ripple free input current or output current by using coupled inductors, which may achieve reduced ...

Giant Current Ripples in Coarse Fluvial Gravel

The Journal of Geology, 1932
Large asymmetrical current ripples were formed from coarse gravel on the floor of a gorgelike channel made in a few hours by a high-velocity stream that partially drained a glacial lake near Ely, Minnesota. The ripples have wave lengths varying from 25 to 60 feet and an average vertical form index of 12.
