Thus, the overall diode conduction loss is
The diode conduction loss
decreases when the duty cycle
increases at a fixed load current
. At
= 0, the diode is ON for the entire cycle, resulting in a maximum conduction loss. At
= 1, the diode is OFF for the entire cycle, and therefore the conduction loss is zero.
Typically, the power loss in the inductor core can be ignored and only the copper loss in the inductor winding should be considered. The inductor current can be approximated by
leading to its rms value
Therefore, the inductor conduction loss is
and the maximum ...
