Constant Ripple Current Control for Switching DC-DC Converter

引用

Journal of Energy and Power Engineering 2012年第9期6卷 1437-1441页

作者： Gwo-Tarng Chern Jenn-Jong Shieh Department of Electrical Engineering Ta Hwa University of Science and Technology Hsinchu 30740 Taiwan

The adapted DC-DC converters should be smaller in size and have a small output current ripple to meet the increasing demand for low voltages with high performance and high density micro processors for several microelectronic load applications. This paper proposes a DC-DC converter using variable on-time and variable switching frequency control enhanced constant ripple current control and reduced magnetic components. The proposed converter is realized by making the turn-offtime proportional to the on-time of the converter, according to the input and output voltage, thereby reducing the corresponding current ripple on output voltage in the continuous conduction mode. A Buck DC-DC converter using the proposed control strategy is analyzed in detail, along with some experimental results to show the performance and effectiveness of this converter.

关键词： Constant ripple current DC-DC converter variable switching frequency continuous conduction mode indirect currentsensor magnetic component.
