| Outline of Final Research Achievements |
In order to realize a high-frequency-transformer, we have focus on evaluations of magnetic properties of magnetic cores. In the laminated block cores made of the high Bs alloy, the rate of increase of iron losses as a function of the magnetic flux density remained small up to around 1.6 T, which cannot be realized in conventional laminated block cores based on amorphous alloy. Under GaN-FET inverter excitation, the iron losses at high carrier frequencies increased because the number of times of ringing. The temperature dependency of iron loss properties was related not only to major loop but also to minor loops.
