“…In [24] a comparison between the calorimetric and the electrical method is made when measuring an active rectifier input LCL filter. In this ultimate case, the first power analyzer can catch only 44% from the actual expected loss and the state-of-the-art power analyzer can measure 91% of the losses with optimal settings.…”

New global energy efficiency classification standard IEC 61800-9-2 for frequency converters and motor systems has been recently launched. It classifies the energy efficiency of the converters and motor-drive systems and introduces three different methods to determine a voltage source converter (VSC) losses for the classification. In here, experimental tests are carried out using the input-output method and the calorimetric method to determine the losses and efficiency of a 160 kW commercial voltage source converter (VSC). The measurement results with these two independent methods are compared and the uncertainty of the methods are analyzed. The converter electric input and output power distributions are analyzed in the frequency domain and are used further to estimate the electric power measurement uncertainty. The measurement uncertainty related to losses obtained with the input-output method is compared with the loss difference between the two methods. This is the first research work to accurately evaluate the experimental methods for the determination of the power losses and examine the validity of the energy efficiency classes of the frequency converters according to new IEC61800-9-2. An urgent need to update the loss boundaries of the IE-classes has been found and the measurement uncertainty effect on the IE-classification is discussed.

“…However, the experience in using them is only now gathering into best practice and it will take time to fully understand their capabilities and assess their true accuracy. In reality, assessing their accuracy will have to be done through comparisons such as reported in [14] and not power analyzer one versus power analyzer two. Figures 1-2 show measurements taken at the output of a VFD operating on a 20hp motor.…”

This paper describes power and efficiency measurement in motor and variable frequency drive systems. The paper first presents an overview of existing international standards relating to motor and variable frequency drives systems and then discusses some of the challenges involved in measuring the power from the pulse-width modulated source. Differences in power measurements due to different power analyzer settings are demonstrated. Two induction motors were tested with sinusoidal supply and variable frequency drive supply to demonstrate power measurement challenges. The results of efficiency tests are compared for a five horsepower motor.

“…[3] Although the heat dissipation of a component can be easily calculated by voltage times current, there is often large error in the electrical method due to the probes delays, phase shifts between sampling channels, sampling errors, nonlinearities of converter, and digital instruments sensitive to noise. [3,4] Calorimetric measurement method [5][6][7] is considered to be an efficient method to measure heat dissipation from a standalone electric device such as magnetic component, capacitor, power converter and transformer, etc. The dissipated power is measured as heat by heat flux sensors when the test chamber reaches thermal equilibrium.…”

A new heat dissipation measurement method based on an external heater and a heat flux sensor was proposed. The information of boundary conditions and thermal properties of materials, such as the thermophysical properties of printed circuit board (PCB), in the heat transfer path is not necessary for heat dissipation measurement in the proposed method.Numerical and experimental study was carried out on testing board with single component to estimate the feasibility of this method, in addition, the effects of the thermal resistance between heater and die/chip on the relative error of the proposed measurement method are investigated. This method is proved to be able to predict the heat dissipation from a single electronic component accurately, and has high applicable for the single BGA component.
