PET-PHD project
Advantages:
High frequency copper winding loss in terms of skin and proximity effect
Determine self and mutual inductance of individual coil
Determine winding loss in terms of non-sinusoidal waveform ( time-vary large signal e.g. inductor current travelling inside boost inductor)
Determine winding and core loss in terms of non-linear magnetic materials( e.g. User can define magnetic materials by BH curve)
