Measurement of Stray-Load Loss in Induction Motors

Transactions of the American Institute of Electrical Engineers, 1945
This paper is written to present test data confirming the accuracy of the reverse-rotation test for stray-load loss24 in polyphase induction motors. This method is the most convenient yet proposed for direct measurement of stray-load losses in squirrel-cage motors, and it is recommended that it be included in the AIEE Test Code for Polyphase Induction ...

Effects of Stray Inductance on Hard-Switched Switched Capacitor Converters

IEEE Transactions on Power Electronics, 2014
Switched capacitor (SC) converters are becoming quite popular for use in DC-DC power conversion. The concept of equivalent resistance in SC converters is frequently used to determine the conduction losses due to the load current. A variety of methodologies have been presented to predict the equivalent resistance in hard-switched SC converters.

Investigation, Evaluation, and Optimization of Stray Inductance in Laminated Busbar

IEEE Transactions on Power Electronics, 2014
Wiring inductance has a critical effect on electrical, thermal, and electromagnetic compatibility (EMC) performances in inverters. Therefore, the low stray inductance laminated busbar, as a state-of-the-art pathway interface, is widely used in high-power inverters.

Experimental and simulative investigations on stray capacitances and stray inductances of power modules

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
This paper presents different experimental methods for measuring parasitic capacitances and inductances of direct copper bond (DBC) based power semiconductor modules. The found parasitics are compared with finite element simulations to evaluate their accuracy. A very good match of the simulated and measured stray capacitances is found.

Stray Load Loss Test on Induction Machines

Transactions of the American Institute of Electrical Engineers, 1934
A loading-back test has been used for the determination of the stray load losss in polyphase induction machines. This test, which was found to have a high degree of accuracy, enables the various losses to be separated. The application of the test is simple and convenient.

Stray load loss tests on induction machines — II

Electrical Engineering, 1936
A new test method is described for the determination of stray load loss in induction machines. By application to given machines, this method is shown to have an exceptionally high degree of accuracy. Values of stray load loss for the same machines are obtained by other recognized methods and results compared.

Investigation on stray inductance of SiC MOSFET module

2017 14th China International Forum on Solid State Lighting: International Forum on Wide Bandgap Semiconductors China (SSLChina: IFWS), 2017
For the past years, high power SiC MOSFET module has been widely applied in industrial drive, power transmission application and high power energy conversion for its superior switching performances. The performance of a commercial available type of three-phase bridge package is investigated to figure out the impact of stray inductance.

Stray losses in squirrel-cage induction motors

Proceedings of the Institution of Electrical Engineers, 1964
The correct understanding of the physical origin of stray losses is essential if machines are to be designed with minimum additional losses.
