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.

Claim (Index 15):
The method as recited in  claim 11 , wherein the following formula relationship for estimating the load resistance value is used in the step of estimating: R L = U out ( 1 - D ) * ( ControllerOut - U comp , ss * D R shunt - U out * ( 1 - D ) * D * T sw 2 * L ) wherein R L  is a value of a load resistance in the path, U out  is a value of the output voltage of the control loop or of the path, ControllerOut is a controller output value of the controller, U comp,ss  is a value of the voltage of a compensation ramp of the step-up converter from peak to peak, D is a duty cycle of the controller, R shunt  is a value of a shunt resistance for measuring the coil current of the step-up converter, L is a value of an inductance of the step-up converter, and T SW  is a period duration of the controller.
