The POE system consists of two core components: PSE (Power Supply Equipment) and PD (Powered Equipment). The PSE is located at the front end of the system and is responsible for combining the power supply with the signal and sending it to the PD, which is

1. Industry pain points and the birth of SPEAlthough traditional Ethernet has been widely used in the upper system of automation architecture, it still faces challenges when connecting the most basic field device layer, mainly manifested in high installat

In today's era of increasingly sophisticated and complex electronic devices, electromagnetic compatibility (EMC) has become a critical threshold for product reliability and market competitiveness. Both weak signals in high-speed transmission and the energy lifeline of stable power supply are constantly threatened by ubiquitous common mode noise. Such noise can, at best, cause data errors and audio-visual distortion; at worst, it may lead to system crashes or even endanger safety. As the "noise filter" of electronic systems, common mode chokes play an indispensable role. However, many engineer
