When iron loss characteristics on an inverter excitation are evaluated by using multiple loads connected in series, they indicate lower iron losses compared with using the loads connected in parallel. It indicates that multiple loads should be connected in series to reduce the iron loss when the loads are excited by one inverter. This phenomenon is caused by semiconductor on-voltages changed by the connection method. This conclusion is introduced by an experimental evaluation using three ring cores made of electrical steel sheets (35H300). In addition, to corroborate the experimental results, a numerical analysis is carried out, in which both of characteristics of magnetic hysteresis and semiconductor are taken into account. Analysis results also indicate the same tendency as the experimental results.

This paper discusses the iron loss and magnetic hysteresis properties of a ring core of nanocrystalline magnetic materials (NMM) at room temperature (RT) and high temperature (HT) under pulse-width-modulation (PWM) inverter excitation. As in the case of the DC hysteresis loop, the coercivity of the NMM ring core at 300 • C (HT) under PWM inverter excitation is larger than that at RT, mainly because of weakening of intergranular magnetic coupling at HT. In addition, in the NMM ring core, the area of the minor loops at HT increases compared with that at RT. Iron loss in the NMM core fed by the PWM inverter increases in tandem with an increase in temperature. Hysteresis loss increases dramatically in tandem with an increase in temperature for every tested case. In a low carrier frequency region, the eddy current loss at 300 • C increases.
