“…However, the behavior of the distorted minor loop and the iron loss under PWM inverter excitation was not examined in detail. The iron loss under PWM inverter excitation is affected by the impedance of inverter circuit, because the distortion of the flux waveform is considerably changed [7]. Also the PWM inverter is usually used under a constant dc voltage and the modulation index is changed in order to control the flux.…”

The pulse width modulation (PWM) inverter is widely used for the control of motors. We showed that the iron loss under PWM inverter excitation is affected by the impedance of the excitation circuit. The dc voltage of PWM inverter, which is widely used, is constant and the control of motor is carried out by changing the modulation index. Therefore, the evaluation of iron loss under PWM excitation with constant dc voltage is necessary in order to investigate the behavior of iron loss in an actual motor. In this paper, we measured iron losses of non-oriented electrical steel sheets under the shingle-phase full-bridge PWM inverter excitation and examined the influence of modulation index , carrier frequency and dc voltage on the iron losses. It is shown that the iron loss under PWM inverter excitation can be reduced when dc voltage is reduced and modulation index is increased.

The influences of sinusoidal and sawtooth periodic carrier frequency modulation (PCFM) on stator steel core loss and rotor eddy current loss of permanent magnet synchronous motor (PMSM) are discussed in this paper. Sinusoidal PCFM and sawtooth PCFM are theoretically analyzed. The reason why stator steel core loss and rotor eddy current loss of PMSM increase when using PCFM is also theoretically investigated. Stator steel core loss and rotor eddy current loss of PMSM driven by fixed frequency pulse width modulation (FFPWM), sinusoidal PCFM and sawtooth PCFM are simulated by finite element analysis (FEA) to discuss the influence of PCFM on stator steel core loss and rotor eddy current loss. FEA results validate that sinusoidal PCFM and sawtooth PCFM increase the stator steel core loss and rotor eddy current loss of PMSM, compared with FFPWM. Keyword: Permanent magnet synchronous motor, Periodic carrier frequency modulation, Rotor eddy current loss, Stator steel core loss.

“…Especially, by using new power semiconductor device, high-speed switching becomes possible, and the loss reduction on power conversion circuit and the miniaturization of circuit become possible [2]- [ 4]. Although the conventional switching frequency, which is called carrier frequency in this paper, was about 10 kHz, it is possible to use until MHz order or so due to the realization of new material devices as SiC or GaN.…”

In order to confirm the iron loss characteristics of electrical steel sheet magnetized by PWM inverter excitation, its carrier frequency characteristics are evaluated by taking account of dead time effect. Usually the iron loss decreases when the carrier frequency becomes large in less than 10 kHz or so.However, the iron loss increase tendency is measured in the higher carrier frequency as 40 kHz. The reason is considered to be that DC voltage increases and it is attributable to dead time in PWM signal phase in this paper.
