Webbased on the Steinmetz Coefficients. This method is commonly known as the Modified Steinmetz Equation (MSE). It allows for the calculation of an equivalent frequency and is motivated by the fact that core loss is dependent on dB/dt (the rate of change of flux density) rather than simply on its level.-1 v m e q s w 2 eq 2 2 0 ˆ 2 P C f B f dB f ... WebHypothesis: p (t) = fcn (B (t), dB/dt) (instantaneous power loss depends only on instantaneous B, dB/dt) Combining C bi i th the iinstantaneous t t di dissipation i ti hypothesis with the Steinmetz equation yields: P (t ) k1 dB dt a B (t) b Tests show that it is not accurate—sometimes worse than MSE MSE. power.thayer.dartmouth.edu 6 MSE …
