Hysteresis Effect Induced Inductance Change and Power Loss for Boost Converter during the Voltage Conversion

Based on the Jiles-Atherton (J-A) model, the differential equation of hysteresis has the different signs at the positive-going and negative-going magnetic fields (H), which is +1 if dH/dt > 0 and is -1 if dH/dt < 0. This implies that an inductor has the different inductances at the current ram...

Summary:Based on the Jiles-Atherton (J-A) model, the differential equation of hysteresis has the different signs at the positive-going and negative-going magnetic fields (H), which is +1 if dH/dt > 0 and is -1 if dH/dt < 0. This implies that an inductor has the different inductances at the current ramp-up time and ramp-down time due to hysteresis sign and remanence magnetization changes. However, this phenomenon is never reported until now. In this paper, the inductance of an inductor larger than the intrinsic inductance at the current ramp-up time and smaller than that at the current ramp-down time are found in a boost converter during the voltage converter.
