Guangdong, China – Nov 9, 2020 – Be it power supply solution, persistent issues with internet devices, photovoltaic power generation or any other problem related to vertical power supply manufacturing, Mornsun always goes toe-to-toe with the complications till a long-lasting solution is reached. Mornsun is a leading China-based company that offers unique and innovative power supply solutions for a range of various devices. The company has a well planned and organized solution for EMC related problems to satisfy the customer’s need once and for all.
Electro Magnetic Compatibility (EMC), the ability of devices and systems to operate in their electromagnetic environment without impairing their functions, has two aspects: Electro-Magnetic Interference (EMI) and Electro-Magnetic Susceptibility (EMS). EMC is related to three issues: disturbance sources, coupling path and sensitive devices. If one of these problems is solved, then the EMC related troubles would not exist.
In order to understand how to diagnose EMC, it is mandatory to know the basics of EMC diagnosis. The main interference sources of EMI are crystal oscillator, switching power supply and electrical machinery whereas the main interference sources of EMS are tests like electrical Surge, Electro Static Discharge (ESD) Testing, Electrical Fast Transient (EFT) and Radio Frequency Interference (RFI).
Besides the sources of interference, frequency is also an important aspect that can be known through various facts. Voice frequency belongs to low frequency while the carrier signal is high frequency. Conducted emissions in EMI belong to low frequency while radiated emission is high frequency. The electrical surge in EMS belongs to low frequency while EFT, ESD, CS and RS belong to high frequency. Gas Discharge Tubes (GDT), Metal Oxide Varistors (MOV), X-capacitors and differential mode chokes are low-frequency elements whereas Common Mode Chokes, Y-capacitors and Electro Spark Detectors are high-frequency elements.
The distinction between Differential Modes and Common Modes also exist. Differential Modes are from line to line while the Common ones are from line to ground. Differential Mode Surge belongs to differential mode and others belong to common mode.
In order to identify and solve an EMI problem, it is essential to run some simple tests like noise positioning. If it seems expensive to identify the complication with a frequency analyzer, it is OK to use some cheaper devices to do pre-tests.
Mornsun is the best helping hand as it offers a well-structured and organized way for EMC related problems. Mornsun has its own way of EMC Diagnosis: first, get to know how a device goes wrong, then analyze possible reasons according to the mechanism of EMC tests and operating principles of the device. Next, adopt measures to verify consumptions one by one. Finally, get the problem solved. The whole process of problem solution clearly manifests that Mornsun serves the purposes of the users in the truest sense.
