Metadata#

Note
1 The power loss includes the losses of all current carrying paths of the component 2 The power loss curve under variable load can be expressed by the formula P= bI² with b as constant. 3 The total load loss curve including no-load loss (constant a) and the variable load loss can be expressed by the formula P=a+bI² .
Remark
intermediate power loss at different load currents can be mathematically derived.
