Abstract
A method for estimating an efficiency of a power device includes identifying a state of operation of the power device, measuring power-related information produced by the power device, and determining an estimated efficiency of the power device based in part on the state of operation of the power device and power loss parameters associated with the power device by using the measured power-related information. Other methods and devices for measuring efficiency are further disclosed.
