PWM inverter-excited iron loss characteristics of a reactor core

Autor: Atsushi Yao, Kouhei Tsukada, Shunya Odawara, Keisuke Fujisaki, Yuji Shindo, Naoki Yoshikawa, Tetsuma Yoshitake

Publikováno v: AIP Advances, Vol 7, Iss 5, Pp 056618-056618-7 (2017)

In this paper, we focus on an evaluation of iron losses in a reactor core under pulse width modulation (PWM) inverter excitation. We examine the inverter- and sinusoidal-fed iron losses of the reactor core through both experiments and numerical simul

Core losses of an inverter-fed permanent magnet synchronous motor with an amorphous stator core under no-load

Autor: Nicolas Denis, Yoshiyuki Kato, Masaharu Ieki, Keisuke Fujisaki

Publikováno v: AIP Advances, Vol 6, Iss 5, Pp 055916-055916-6 (2016)

In this paper, an interior permanent magnet synchronous motor (IPMSM) with a stator core made of amorphous magnetic material (AMM) is presented. The IPMSM is driven by a voltage source three-phase inverter with classical pulse width modulation (PWM)
