Abstract
A method for optimizing the operation of a digital controller provided in a control loop for a step-up converter. The method includes: evaluating at least one output variable of the digital controller during operation of the step-up converter; estimating the instantaneous load resistance value in the path of the control loop based on the at least one evaluated output variable; setting at least one controller coefficient of the digital controller based on the estimated instantaneous load resistance value during operation of the step-up converter. A change in the setting of the at least one controller coefficient results in a change in the transition frequency in the control loop. Furthermore, a control loop for a step-up converter that includes a digital controller is provided, which is configured to carry out the steps of the method. A computer program product that includes computer-executable program code for carrying out the method.
