Abstract
The DC-DC power converters have extreme importance incontemporary 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.
