Latest Technical Paper “Accurate Efficiency Measurements” Scope The objective of this white paper is to specify a standard, how to determine efficiency of AC-DC and DC-DC power supply units (PSU) accurately and comparably. Thermal steady state is assumed unless stated otherwise. Deviating measurements result either from random or systematic error. Random errors mainly in the device under test (DUT) are caused by unknown and unpredictable parameters like parts tolerances, which can mostly be described by a Gaussian normal distribution. By referring to a reference DUT, random errors can be neglected in this guide. The focus is on minimizing systematic errors like: • measurement setup (source, sink, wiring, mounting) • environmental conditions of the DUT (temperature, altitude) • instrument inaccuracy (range, temperature drift) 8
