CPC H02M 1/0058 (2021.05) [H02M 3/158 (2013.01); H02M 1/0003 (2021.05)] | 22 Claims |
1. A voltage converter device comprising:
one or more inductive elements to deliver inductor current to an output section of the voltage converter device;
at least one switching device to control current flow at the output section of the voltage converter device; and
a controller to controllably vary, according to a predictive model that corresponds to a cost function, a subsequently applied switching frequency to the at least one switching device to maintain zero-voltage switching based, at least in part, on the inductor current of the one or more inductive elements, wherein, to controllably vary, according to the predictive model that corresponds to the cost function, the subsequently applied switching frequency, the controller is configured to vary the subsequently applied switching frequency according to an optimization process that uses the cost function.
