POWER INDUCTOR SELECTION
The inductor is one of the two energy storage elements in a
boost converter.
Figure 11
shows how the inductor current
varies during a switching cycle. The current through an
inductor is quantified as:
If V
L
(t) is constant, di
L
(t)/dt must be constant. Hence, for a
given input voltage and output voltage, the current in the
inductor changes at a constant rate.
