Improved Core-Loss Calculation for Magnetic Components Employed in Power Electronic Systems (2012, methodology): “The built test system consists of a power stage, a power supply, an oscilloscope and a heating chamber The reader is referred to [17] for more information about the test setup, including a detailed accuracy analysis of the loss measurement.”
Comparative Evaluation of Three-Phase AC–AC Matrix Converter and Voltage DC-Link Back-to-Back Converter Systems (2012, methodology): “If the Steinmetz parameters were known as a function of the dc bias of the core, the HF core losses could be determined by a calculation approach based on the modified Steinmetz equation according to [14].”
Loss modeling of inductive components employed in power electronic systems (2011, background): “Another means of describing core losses under DC bias condition is shown in [14]: a graph that shows the dependency of the Steinmetz parameters (α, β and ki) on premagnetization is introduced.”
Improved core loss calculation for magnetic components employed in power electronic system (2011, background): “This is discussed in [12], where a graph showing the dependency of the Steinmetz parameters (α, β and k) on premagnetization is introduced.”
