Abstract :
The Steinmetz equation is applied in a pure hysteresis part and a remaining part following a dB/dt behavior. A double natural Steinmetz extension method for non-sinusoidal waveforms is proposed (DNSE). Tests have been done at 100 kHz square waves for half bridges with variable duty ratio and full bridges with variable phase shift
