Tips: Why should users connect switching power supply to ground?

Ground wiring was introduced as a protective measure to prevent electric or electronic devices from thunder strike. It aims to lead current generated by thunderbolt to ground, so as to protect buildings. At the same time, ground wiring is an effective means to protect personal safety. When phase lines get connected to shells of devices because of certain reasons (such as defective insulation or aging lines), shells of devices will generate voltage which could endanger people's life. However, the current generated by defects of devices can be introduced to ground by PE to protect personal safety. With development of digital communication and other digital areas, functions of ground wiring have stepped beyond its original portfolio of lightning and safety protection. In communication systems, interconnection of devices requires a place to be the benchmark. Electronic devices are becoming more complicated and their signal frequency appears much higher, so noise in signal communication and electromagnetic compatibility must be attached importance. Improper ground wiring may have negative influence on reliability and stability on system operation. Recently, backflow of high-speed signals also introduced the concept of ground wiring.
