Where “D” is the duty cycle [T
element.
Boost applications can work in two main cases:
●
●
depending if the current on inductor becomes null (DCM), or not (CM), within the switching
period.
Figure 7.
Even if a boost converter can work both in CM and DCM, the efficiency is normally higher
when it works in CM, if the switching frequency is maintained constant.
Inductance and switching frequency (F
the system working in CM following rule should be used:
Worst case for L is the above formula is D = 50%.
