A.
T he current equation is different in CCM or DCM with different inductance, but no paper proposed the analytical equation to describe it. This paper is devoted to the accurate equation of the inductor without referring to how to design the inductor and select the power device and its heat sink.
B.
Although the current equation is known to be different in CCM or DCM with different inductance, no paper proposed the analytical equation to describe it. This paper is devoted to the accurate equation of the inductor with no reference to how to design the inductor and select the power device and its heat sink.
