Modeling strategies for estimating and suppressing electromagnetic interference and improving power integrity
… board. Here, simple and accurate inductance models of 2- and 8-terminal capacitors including connections to the power and return plane are developed. Circuit models of the capacitors and layout are created using the partial equivalent element circuit method which provide options for …

Passive Cancellation of Common-Mode Electromagnetic Interference in Switching Power Converters
It is well known that common-mode (CM) conducted electromagnetic interference (EMI) is caused by the common-mode current flowing through the parasitic capacitance of transistors, diodes, and transformers to ground in the power circuit. Because of the potential for interference with other systems as …

Modeling strategy for EMI filter and flyback transformer
“The switch-mode power supply is key to miniaturizing power adapters. However, the switching nature of the circuit introduces issues in conducted emissions. In a flyback converter, the transformer serves as the path for common mode current flowing from the primary side to the secondary side. …

Design and Validation of a High-Density 10 kV Silicon Carbide MOSFET Power Module with Reduced Electric Field Strength and Integrated Common-Mode Screen
… ringing and voltage overshoot. An integrated common-mode current screen contains the current that is generated by these fast voltage transients within the power module, rather than flowing to the system ground. This screen connection simultaneously increases the partial discharge inception …

High Frequency Bi-directional DC/DC Converter with Integrated Magnetics for Battery Charger Application
… totem-pole AC/DC in critical conduction mode (CRM) to realize zero voltage switching (ZVS), is operated at over 300 kHz. A bi-directional CLLC resonant converter operating at 500 kHz is chosen for the second stage. Instead of using the conventional fixed 400 V DC-link voltage, a variable …
