Abstract
Commutations of power IOBT modules used in power converters cause high voltage and current gradients in the collector waveforms, that 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 radio frequency conducted current flowing in the assembly. Frequency and amplitude of the internal oscillating currents are simulated by means of a suitable IOBT module model. Diagram of irradiation is measured in anechoic chamber at different frequencies, connecting IOBT gate to radiofrequency generator. Presented results are precise within 3dB limit.
