A Guide to Flyback Transformers | Coilcraft may be designed for CCM, DCM, or both. Flyback transformers may operate in both CCM and DCM modes, depending on the input voltage and load conditions. When designing a flyback transformer, the worst-case condition of maximum load at the minimum input voltage creates the highest (peak) primary current requirement.

Substation Health Risks | EM Watch(Electrical engineers know how to design equipment that emits less EMF, but decades ago few people worried about it.) Cabling and switchgear inside the substation are generally mounted on one of the side walls. The transformer is nearby, usually floor-mounted. So the EMF outside one wall of the substation may be stronger than from the opposite side.
