This functional group shows the power consumption of the transformer / Converter, taking into account the losses in the core, as well as losses on the key and on the diodes for the DC-DC Converter. Core losses are indicated by the range for minimum and maximum input voltages. At SELECTion of turns of a primary loss are recalculated.

For FlyBack on the ring with the specified parameters Al (inductance coefficient) and DCB core losses are not calculated.

Attention! The calculation of losses is correct only for a ferrite core on a material with a magnetic permeability of 2200±25% (if the magnetic permeability is significantly different, the calculation is not correct). The calculation is carried out according to the approximating formula, the accuracy of the calculation is different for different parameters. For other types of material calculation is incorrect.
