Explore Radiated Electromagnetic Interference due to Differential Mode Voltages on A Power Converter PCB
This paper investigates a novel mechanism of radiated electromagnetic interference (EMI) in power converters. Experimental results reveal that the differential-mode (DM) voltage between input power terminals can serve as a significant excitation source for radiated EMI, particularly when the PCB layout of the power delivery paths is highly unbalanced. A radiation theory is developed based on electromagnetic theory to explain this phenomenon. Using the proposed theory, the primary contributors to radiation are identified and experimentally validated. An EMI mitigation technique is then proposed and verified through measurements. Finally, the applicability of the theory is extended to a broader range of scenarios.

Modeling of Low-Frequency Radiated EMI From the Inductors of Power Converters in Electric Vehicles
This paper first identifies the power inductor as a major radiated EMI source in a power converter in electric vehicles at low frequencies. To understand the radiation mechanism and predict radiated EMI for the power converter, the radiation model is developed for the inductor based on electric dipole moment theory. The inductor’s CM voltage is identified as the dominant contributor to the radiated EMI at low frequencies. The impacts of the PCB ground and CISPR25 EMI measurement setup for electric vehicles on the radiated electric field were also investigated. The proposed prediction technique is experimentally verified and extended to inductors with different shapes.

Modeling and Prediction of Low-Frequency Near-Field Radiation for a Power Converter Based on the Operating Principle of a Monopole Antenna
This article develops a model to predict the measured near-field radiation via a monopole antenna based on the test setups specified by the EMI standards such as CISPR 25, DO-160E, MIL-STD-461E. The article first identified a major near-field radiation source in a dc–dc power converter. The operation principle of the monopole antenna is then studied, and a model is developed to predict the output voltage of the antenna. Next, the transmission line effect in the EMI test setup is identified and its impact on the measured radiated EMI is modeled. A prediction technique is developed for the low-frequency near-field radiation. Finally, experiments validated the developed theory.
