Let's cut to the chase: power inductors absolutely can store energy, but not in the way your smartphone battery does. Picture this – it's like comparing a water balloon to a hydroelectric dam. Both handle H 2 O, but their storage game is completely different.
[pdf] The energy stored (W) follows this simple-but-powerful formula: Where L is inductance (measured in Henrys) and I is current. Double the current? Quadruple the energy storage! This quadratic relationship makes inductors particularly valuable in high-current applications like industrial motor drives [1].
