The mechanism of common-mode noise current in control and gate-drive circuits on a chopper circuit is discussed. For high power density configurations, common-mode noise current flows not only in the main circuit, but also in the control and gate-drive circuits. This noise current increases the risk of control circuit misoperation, and might flow out from control and gate-drive circuits and interfere...
In order to increase the power density of power converters, reduction of the switching losses at a high-frequency switching condition is one of the most important issues. This paper presents a new gate drive circuit that enables to reduce the switching loss on both the power MOSFET and the IGBT. A distinctive feature of this method is that both the turn on loss and the turn off loss can be decreased...
This paper discusses the iron loss characteristics of magnetic materials used in the chopper circuits of pulse width modulation (PWM) inverter circuits. A distinctive feature of this method, previously reported by the authors, is that the iron loss map is created by measuring the dynamic minor loop traced on the B-H plane, and it can be a useful method for calculation of the inductor iron loss in...
