The DC-DC power converters have extreme importance in contemporary applications. Moreover, the DC-DC power converters are the ideal candidates in numerous applications such as electric and hybrid vehicles, fuel cells and others. They have been extensively researched upon over three decades. The control of these converters has been often implemented using PWM techniques and based on discrete components and integrated circuits. In this paper we propose a systematic approach for the control of step down DCDC converters with variable input voltage based on discontinuous control action. We demonstrate that the proposed algorithm achieves robustness to variations of the converter load and the input voltage without additional sensors
