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...
Spurred by the industrial demands for terabyte/s bandwidth graphics module, high bandwidth memory (HBM) has been emerged to overcome the limitations of conventional DRAMs. Additionally, due to the fine pitch and high density interconnect routing between GPU and 4 HBMs in 2.5D terabyte/s bandwidth graphics module, HBM interposer has also been to the force. However, several signal integrity issues of...
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...

In this study, an inverter model including non-ideal Insulated Gate Bipolar Transistors (IGBTs) characteristics and a busbar model using impedance measurement is proposed. A motor drive system in Hybrid Electric Vehicle (HEV) consists of a battery, an inverter, a cable, and an electric motor. The inverter is not only a voltage source, but also one of the principal noise sources in the motor drive...
