Patent ID: 8587962

Claim:
An electrical system comprising: an input interface; an output interface; a first energy conversion module coupled between the input interface and the output interface, the first energy conversion module including one or more switching elements; an inductive element coupled electrically in series between the input interface and the first energy conversion module; and a control module coupled to the first energy conversion module and the inductive element, wherein the control module is configured to: determine an estimated voltage loss for the first energy conversion module based on a current through the inductive element; obtain a measured output voltage at the output interface; add the estimated voltage loss to the measured output voltage to obtain a compensated output voltage; determine a compensated duty cycle control value for operating the first energy conversion module to produce a desired voltage at the output based at least in part on the compensated output voltage, wherein the compensated duty cycle control value is influenced by a current through the inductive element and accounts for voltage across the one or more switching elements while operating the first energy conversion module; and operate the one or more switching elements of the first energy conversion module to deliver energy to the output interface with a duty cycle that is influenced by the compensated duty cycle control value.
