Summary: This paper proposes a new configuration of neutral point-based common mode active electromagnetic interference filter. By setting the reference of the filtering system to the neutral point of the equipment, the filter is able to sense and cancel the common mode noise without the need for additional noise separation devices.

Summary: This article proposes a separate floating heatsink based suppression method (SFHBSM) to effectively suppress high-frequency conducted common-mode (CM) electromagnetic interference (EMI) by improving both the CM EMI source and the propagation path. The SFHBSM achieves nonringing CM EMI source and provides effective blocking for the CM EMI propagation in the high-frequency domain. Experiments show that SFHBSM achieves EMI reduction in almost the whole high-frequency domain with up to 35 dB attenuation in a two-level three-phase power converter.

Summary: The increasing concern of electromagnetic interference (EMI) conducted emissions (CE) in power electronics is due to the high switching frequency and fast switching speeds of the latest generation of wide-bandgap semiconductors. A systematic EMI filter design is achieved by decomposing the total conducted EMI noise into common-mode (CM) and differential-mode (DM) parts using a CM/DM noise separator. However, asymmetries in the EMI test setup can lead to unwanted conversion between CM and DM EMI noise, significantly influencing the CM/DM EMI separation.

Summary: Recent developments in semiconductor technology and power packaging have enabled converter implementations with increased efficiency and power-density. However, increased switching performance has also resulted in elevated conducted emissions signatures. This study applies a systematic method to isolate the common-mode behavior of a boost converter topology and identifies the elements of greatest importance to the conducted emissions profile. The developed common-mode equivalent model (CEM) is validated through empirical studies and a procedure for suppressing conducted emissions is introduced.

Summary: This article comments on a published paper by Zhang and Wu (2019) on the topic of common-mode noise reduction by parasitic capacitance cancellation in a three-phase inverter. The paper demonstrates how a three-terminal electromagnetic interference (EMI) filter can effectively reduce EMI noise on the output side. The concept of parasitic capacitance cancellation is not new, and previous works by Wang and Lee (2007, 2010), Neugebauer and Perreault (2006), and Piboonwattanakit and Khan-Ngern (2008) should be cited.

Summary: In this article, a hybrid active modulation approach is proposed to tackle the challenges faced by conventional pulsewidth modulation (PWM) strategies in the aircraft electric starter/generator system. The proposed approach includes coordinate-based PWM for startup process and enhanced carrier-based virtual-space-vector modulation technique for generation mode. Bias-offset injection in the time and voltage domain is used to maintain balanced capacitor voltages. Simulation and experimental results obtained from a test rig validate the effectiveness of the presented algorithm.

Summary: This article proposes a new output active common-mode filter (ACF) to reduce electromagnetic interference (EMI) and protect motor bearings by compensating for the steep rising/falling edges of common-mode voltage. An input ACF is also necessary to attenuate the injected common-mode noise. The holistic assessment of input and output ACFs for inverter-fed motor drive systems is demonstrated, ensuring compliance with the CM EMI standard.
