Experimental validation for an open-loop LCLC output filter buck converter Conference Paper uri icon

abstract

  • In this paper the experimental validation of the open-loop operation for a buck converter with an LCLC filter at the output is addressed. This DC-DC buck converter has a significant reduction of output switching ripples and an increase of power density compared to the buck conventional topology. Moreover as passive components are less demanding, the implementation may be performed by using film capacitors. Hence the converter mean time failures can be made higher than for the conventional buck converter. These features can be applied in efficient renewable electric energy systems, in sensitive power sources and in sensitive loads. In this paper it is shown that by adequately selecting the passive elements, the open-loop oscillating behaviors may be highly alleviated which makes of the converter a suitable solution. Experimental results are presented to show the performance of the converter. © 2017 IEEE.
