•
Boost inductor L
The important parameters for selecting the boost inductor are:
•
•
•
The maximum average inductor current is:
The ripple current through the boost inductor is:
The peak current through the boost inductor is:
(The peak current trough the boost inductor must be smaller than the saturation current threshold!)
The RMS current through the boost inductor is:
The boost inductor value L
