2 Ttotal Vin min ) Vin min Another design criterion is the high current ripple in CRM. As a result of the high ripple, the core flux swing is bigger compared to the CCM mode. Higher flux swing results in higher core losses and rules out materials such as powdered iron. Detailed discussion on properties of the material is beyond the scope of this paper, but it is something to keep in mind in the design of the inductor. It is apparent from the above equations that the follower boost approach...
