Abstract
A DC-DC converter including a DC input and a DC output, at least one switch connecting the DC input to a converter inductor, the converter inductor connecting the at least one switch to the DC output, a controller configured to control an open/closed state of the at least one switch, a first voltage sensor connected to the DC input and operable to provide a sensed voltage to the controller, a second voltage sensor connected to the DC output and operable to provide a sensed voltage to the controller. The controller includes a processor and a memory, the memory storing instructions for causing the controller to dynamically adjust a duty cycle limit of the DC-DC converter to be equal to one minus a numerator divided by a denominator, where the numerator is the instantaneous input voltage minus a compensation factor and where the denominator is the instantaneous output voltage.
