“…Stimulus for oscillation can be attributed to the voltage variation during commutation and this was demonstrated in. A similar model has been used recently in [5] in order to predict the conducted noise, but also in this case the irradiated noise cannot be calculated.…”

“…The solution to such problem is awkward as electro-mechanical device characteristics and electromagnetic structure properties are coupled and have to be considered. Several studies on the topic have been presented but they are focused on the device behaviour [2,3,4] only, either on the electromagnetic structure irradiative properties [5,6]. More several papers focused on IGBT device modelling and parameters extraction [2,7] and proposed different radio frequency models.…”

Commutations of power IGBT modules used in power converters cause high voltage and current gradients in the collector waveforms, which can generate and irradiate very high electromagnetic noise levels. An innovative experimental-simulative method is presented, which is able to predict irradiated noise levels during converter operation: such method allows power electronics designer to have a proper and simple method to predict spectrum and amplitude of irradiated noise during converter operation, in order to ensure a direct compliance with the enforce normative. The irradiated noise is generated by high frequency conducted current flowing in IGBT module and in the converter. Frequency and amplitude of the internal oscillating currents are simulated by means of a suitable IGBT module model proposed in the past and now optimized for irradiation simulation. The irradiated field during converter operation can be calculated by means of a preliminary static measure executed in anechoic chamber, where the diagram of irradiation of the system is measured at different frequencies, connecting IGBT gate to a radiofrequency generator. Presented results are precise within 3dB limit.
