A. Boglietti et al., CHANGE OF THE IRON LOSSES WITH THE SWITCHING SUPPLY FREQUENCY IN SOFT-MAGNETIC MATERIALS SUPPLIED BY PWM INVERTER, IEEE transactions on magnetics, 31(6), 1995, pp. 4250-4252
In the paper change in iron losses due to the switching frequency in s
oft magnetic materials supplied by PWM inverter, is analyzed. Experime
ntal tests with several samples of material and switching frequency fr
om 1 kHz up to about 20 kHz, are reported. Values of iron losses vs sw
itching frequency, for different values of the fundamental flux densit
y and assigned modulation parameters, are presented for the materials
investigated.
