What is continuous and discontinuous conduction mode?
During continuous conduction mode, the inductor current in the energy transfer never reaches zero value. In the discontinuous conduction mode, inductor current is not persistent throughout the complete cycle and reaches zero level earlier even before the end of the period.
What causes discontinuous conduction mode?
The discontinuous conduction mode arises when the switching ripple in an inductor current or capacitor voltage is large enough to cause the polarity of the applied switch current or voltage to reverse, such that the current- or voltage-unidirectional assumptions made in realizing the switch with semiconductor devices …
What does continuous conduction mode mean?
Continuous Conduction Mode (CCM) is characterized by current flowing continuously in either the primary or the secondary windings. The secondary current ramps down supplying energy but does not reach zero before the TOPSwitch turns back on at the beginning of the next cycle.
What is DCM electrical?
Alternately, if tOFF lasts long enough for the primary inductor to completely discharge, then there is a period of time during which the current in the inductor is zero. This causes both the diode and the MOSFET to be in an off state, and is called discontinuous conduction mode (DCM).

What’s the difference between DCM and continuous conduction mode?
This operation is called continuous conduction mode (CCM). Alternately, if tOFF lasts long enough for the primary inductor to completely discharge, then there is a period of time during which the current in the inductor is zero. This causes both the diode and the MOSFET to be in an off state, and is called discontinuous conduction mode (DCM).
