1. A system comprising:
- a power converter configured to convert an input voltage to an output voltage for providing power at an output thereof to which a load is connectable; and
a measurement system that comprises measurement circuitry configured to measure an average of an accessible current in the power converter and derive an average measurement of another current in the power converter based on a timing control signal used to control operation of the power converter.

Abstract
One example of the invention relates to a power system. The power system can include a power converter configured to convert an input voltage to an output voltage for providing power at an output thereof to which a load is connectable. A measurement system can include measurement circuitry configured to measure an average of an accessible current in the power converter and derive an average measurement of another current in the power converter based on timing control signals used to control operation of the power converter.

12. A power system comprising:
-
an input source to supply input power; a power converter configured to convert the input power to an output power, the power converter comprising; a switch to conduct a switch current in response to a timing signal having a timing period; an inductor to conduct current based at least in part on the switch current; a rectifier configured to conduct current based at least in part on the switch current; and a measurement system configured to provide a measure of average current through the switch during a selected portion of the timing period, the selected portion of the timing period depending on a topology of the power converter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
