Firstly, this paper establishes an equivalent magnetic circuit model for the TSWIM and deduces the decoupling condition by mitigating the coupling effect between each winding. To select a suitable core model, c

Power inductor with reduced DC current saturationSUTARDJA SEHAT
In the balancing operation, the switch of the high-charged battery cell, M11 for Cell1 or M12 for Cell2, turn on and the energy is stored in the inductor. When the inductor current reaches the peak, this switch is turned off and the energy on the inductor is transferred to the low-ch...

This paper implements variable inductance by combining a core with magnetic saturation and a core without magnetic saturation, slightly different from the general design method. Step 1: in Case 1, the allowable ripple current of the inductor is first calculated by Equation (17), considering the...
"Inductor current saturation rating should be larger than the possible peak inductor current to ensure proper operation" - In these tests, all of the inductors have higher higher current saturation ratings than the possible peak inductor ...
