Some procedures in mitigating conducted electromagnetic interference

Susceptibility of ICs to Conducted Electromagnetic Interference

This work is focused on the susceptibility of integrated circuits (ICs) to electromagnetic interference (EMI). The main issue is simulation and measurement on device level and circuit level. The work gives an overview of the overall electromagnetic compatibility (EMC) issues, and shows Direct Power Injection (DPI) measurement technique for conducted electromagnetic interference.

Analysis of the Heatsink Influence on Conducted and Radiated Electromagnetic Interference in Power Electronic Converters

Novel Frequency Swapping Technique for Conducted Electromagnetic Interference Suppression in Power Converter Applications

Abstract: Quasi-resonant flyback (QRF) converters have been widely applied as the main circuit topology in power converters because of their low cost and high efficiency. Conventional QRF converters tend to generate higher average conducted electromagnetic interference (EMI) in the low-frequency domain due to the switching noise generated by power switches, resulting in the fact they can exceed...

A Novel Measurement System for the Common-Mode- and Differential-Mode-Conducted Electromagnetic Interference

Electromagnetic Interference (EMI) test is an important part for the manufacture of power electronic equipment, which helps us not only analyze the noise characteristics of the Equipment Under Test (EUT) but also design EMI filters. The previous separation method for the Common Mode (CM) and Differential Mode (DM) noise was time consuming or costly. In this paper, a novel measurement system for...

Mitigating Inter-network Interference in LoRa Networks

Long Range (LoRa) is a popular technology used to construct Low-Power Wide-Area Network (LPWAN) networks. Given the popularity of LoRa it is likely that multiple independent LoRa networks are deployed in close proximity. In this situation, neighbouring networks interfere and methods have to be found to combat this interference. In this paper we investigate the use of directional antennae and th...
