Abstract
This paper describes a mechanism and reduction methods of EMI radiational noise on IGBTs. The radiational. Noise is generated by oscillating current flowing through the IGBTs output capacity and the snubber circuit. The oscillating current is forced to flow by the high dv/dt rates of the IGBT switching operation. The radiational noise can be analyzed by frequency evolution of the oscillating current. In addition, it is indicated that using a di/dt control gate drive circuit is effective as a means for reducing the radiational noise. The effect of this method has been verified by experimental and simulational results.
