This work considers the coupling effects between differential and common modes, which have an impact on the conducted electromagnetic noise generated by variable speed drive supplied from DC grid of an aircraft. Common mode noise, which origins from the differential mode, was observed during conducted EMI measurements at the output shielded cable, due to asymmetry of the cable. It is shown, that such...
With upcoming trends of multiband, broadband and ultrawideband transmitters, there is a need for understanding and representing nonlinear transmitter behavior at system level at frequencies other than transmitter frequency, which might fall within the working range of ultra wideband power amplifier (PA) or other PAs. This paper presents characterization setup, data time-alignment technique and modeling...
This paper deals with the fractional order modelling of the supercapacitor voltage response for a given current profile. The model is obtained using the porous electrode theory applied on the supercapacitor case. In order to simplify the complexity of the model, it is assumed that there is no diffusion process in the electrolyte. These assumption leads to neglect the supercapacitor self-discharge...
