Based on a modification of the Steinmetz equation, simple and general formulas suitable for magnetic power loss estimation in converter design are proposed. Using only the manufacturer data sheet parameters for sinusoidal waveforms, it is possible to estimate the core losses in symmetrical converters. A loss model is introduced to consider the loss increment caused by DC magnetization bias in asymmetrical converters, giving worst case criteria to design the magnetic components.
