9.3.1. Main constraints in the inductor design
The starting point for an inductor design is the stored energy relation (Eq. [9.31]) defined by the inductance L, the inductor peak current (
), the RMS current (IL), the RMS current density (JL), the peak flux density (BL), the winding conductor fill factor (kwc), the winding window area (Aw) and the core area (Acore) (Mohan et al., 2003).

[9.31]
The product (Aw·Acore) appears in Eq. [9.31] and is an indication of the core size and it is called area product. ...
