The grid-shaped core (a) has the same D_out as the I-shaped core (D_out = 10.5 cm, h = 2.5 cm, and W = 1 cm); the grid-shaped core (b) has the same volume as the I-shaped (D_out = 18.5 cm, h = 2.5 cm, and W = 1 cm); (c) the schematic of the grid-shaped magnetic flux collector plate for both grid-shaped cores.
