We describe a history-dependent (non-Preisach) hysteresis model based on direct use of experimental first-order reversal curves. We propose that any second or higher order reversal curve can be constructed by using internal segments of the firstrorder reversal curves, and show that particular transplants (segments with required overall dimensions △H, △B) can always be found in both the B and H directions from a current turning point. This makes it possible to obtain the reversal curve originating from this point as a weighted sum of the transplants found in those directions. The effectiveness of the proposed model is illustrated by its use in simulation of the complex transients in a conducting ferromagnetic sheet subjected to a pulsewidth-modulation voltage supply.
