High-speed Core Loss Base Data Collection for Core Loss Calculation Under Power Electronics Converter Excitation
نویسندگان
چکیده
The calculation of core loss power electronics converters requires a large number data, including the excitation frequency, flux density ripple, and DC magnetic field bias characteristic under rectangular voltage excitation. However, in case conventional method (that employs B-H analyzer with chopper circuit), very long time is required to collect this base because circuit parameter tuning needed for each measurement point. Therefore, we propose high-speed data collection converter was substantially reduced upon usage pulse width modulated (PWM) inverter neural network various characteristics were expressed PWM inverter, these losses learned by network. as measured via proposed methods, compared validate accuracy method, difference found be lesser than 12%. Thus, achieves collection.

A practical approach for magnetic core-loss characterization - Power Electronics, IEEE Transactions on
A practical approach for magnetic core-loss characterization up to a few megahertz is presented. An error analysis is for the first time performed, revealing that corrections are needed to compensate for errors introduced by the extra phase shift inherent in a measurement setup, and by shunt parasitic capacitance associated with an inductive device under test. A simple technique is then propose...
متن کاملUltrafast Core-Loss Spectroscopy
Electron microscopy (EM) has evolved into a tool of tremendous value to determine the structure of materials down to the atomic level. The time resolution in EM is typically too slow to resolve fast catalytic reactions or phase transformations. Here, we demonstrate core-level spectroscopy in ultrafast (4D) electron microscopy as a new method to follow element-specific structural dynamics with f...

Core Loss Analysis of Interior Permanent Magnet Synchronous Machines under SVPWM Excitation with Considering Saturation
Core loss is one of the significant factors affecting the high power density of permanent magnet machines; thus, it is necessary to consider core loss in machine design. This paper presents a novel method for calculating the core loss of permanent magnet synchronous machines under space vector pulse width modulation (SVPWM) excitation, taking magnetic saturation and cross coupling into account....
