Discontinuous Control Analysis for Step Down DC-DC Voltage Converters

Abstract

The DC-DC power converters have extreme importance incontemporary applications. Moreover, the DC-DC power converters are theideal candidates in numerous applications such as electric and hybrid vehicles,fuel cells and others. They have been extensively researched upon over threedecades. The control of these converters has been often implemented usingPWM techniques and based on discrete components and integrated circuits. Inthis paper we propose a systematic approach for the control of step down DCDCconverters with variable input voltage based on discontinuous controlaction. We demonstrate that the proposed algorithm achieves robustness tovariations of the converter load and the input voltage without additionalsensors.
