WebSo we’re talking CCM, DCM and CrCM (BCM) Continuous conduction CCM and discontinuous conduction modes DCM refer to whether the current in the energy storage element (inductor) in buck or boost derived circuits goes to zero each switching cycle or not. In CCM it does not reach zero so at the end of every switching cycle there is some … WebSep 9, 2024 · In a buck converter, the selection of inductor determines at what conduction mode the converter is operating. Selecting the inductor for the buck converter above the critical value (L> Lcritical) makes the converter operate in CCM. In a buck converter, the average output voltage is lower than the input DC voltage
