Abstract
An electric switch-mode power converter comprises: a parameter predictor for predicting and updating at least one regulator parameter of a regulator controlling a switching device of the converter, a performance feedback signal generator for providing a performance feedback signal indicative of a performance of the conversion operation, wherein the parameter predictor is configured to predict an update of the regulator parameter based on the performance feedback signal and during update intervals, the intervals being during the power conversion operation and being separated by pauses without update.
Claims20
An electric power converter for converting input quantities, namely an input voltage Vin and an input current Iin, into converted output quantities, namely a converted output voltage Vout and a converted output current Iout, the electric power converter comprising:
- an input terminal for receiving the input quantities;
- an output terminal for outputting the converted output quantities;
- a switching device to be switched for a conversion operation of the electric power converter, the switching device having a control terminal;
- a regulator connected to the control terminal, the regulator controlling the switching device based on at least one regulator parameter;
- a parameter predictor operative to carry out a prediction of the at least one regulator parameter and updating the at least one regulator parameter of the regulator based on the prediction;
- a performance feedback signal generator connected to the output terminal of the electric power converter, the performance feedback signal generator operable to produce a performance feedback signal indicative of a performance of the conversion operation;
- and
- the parameter predictor operative to predict and update the at least one regulator parameter based on the performance feedback signal during update intervals, the update intervals taking place during the power conversion operation and being separated by pauses during which no update of the at least one regulator parameter is carried out.
