A DC-AC power inverter contains parasitic inductances in a DC-linked wire and a load wire. These parasitic components may cause oscillation in the output voltage of the inverter, and cause electromagnetic interference (EMI) issues to other power electronic circuits in the system. In this paper, an effect of the parasitic inductances on the DC-linked wire and load wire of the power inverter are analyzed...
Simultaneous switching noise (SSN) occurs when clock synchronized core circuits switch simultaneously. Furthermore, a huge amount of the SSN generated by simultaneous switching current (SSC) with high power distribution network (PDN) impedance at anti-resonance can cause electromagnetic interference (EMI) problems and logic failure. In multi-core processors, the spectrum of SSC is varied by power...
The output voltage and current from dc-ac inverter generate switching noises and may cause electromagnetic interference (EMI) problems to other electronic systems. To analyze high frequency switching behavior of an inverter accurately, an accurate IGBT model is essential. In this study, an insulated gate bipolar transistor (IGBT) is modeled using datasheet and measurement data to analyze the high...
