Abstract
A system measures power conversion efficiency of a voltage regulator. A measurement setting module presets a maximum output current and a total measurement number, and calculates each target output current of the voltage regulator. A load adjustment module adjusts an impedance of the electronic load to equal current passing through the electronic load to the target output current of the voltage regulator. A calculation module calculates each output power and input power, and power conversion efficiencies for each sequence number of measurement.
