Abstract
A switched power converter includes a power stage. The power stage includes a sensor for sensing an output current to obtain a sensed output current, a sensor for sensing an output voltage to obtain a sensed output voltage, and a sensor for sensing an input voltage to obtain a sensed input voltage. The power converter further includes a look-up table or mathematical relationship implementation for deriving an efficiency measure of the power converter from the sensed input voltage, the sensed output voltage and the sensed output current by relating an energy taken by a load and an energy delivered by the input voltage for a specific period of time.
