SUMMARY OF THE INVENTION [Technical Field] The present invention relates to a power system, and more particularly to a power system for use in a power line communication device to reduce a signal loop. [Prior Art] With the rapid development of information and communication technologies and the increasing popularity of broadband network environments, it is an inevitable trend to create an intelligent and digitalized life. In the overall home network, products, such as computers, home appliances, and consumer electronics, can pass through wireless local area networks (WLANs), power line communication (PLC), and home telephone line networks (Home Phoneline Networking Alliance). , HomePNA) or coaxial, but directly use the power line already existing in the home as a network, with the advantages of easy, plug-and-play, beautiful appearance, etc., so power line communication has become a close concern of all domestic appliance manufacturers or Tonglang Road operators.

However, since the power signal of the power line communication module 130 itself is transmitted from the % source supply state 11 to the motherboard 120, the host board 12 is transferred to the power line communication module 13 by the Dili line 140. 〇, thus causing the power supply loop to be too large, and it is easy to g the antenna effect to call the electromagnetic interference of the power supply noise (electromagnetic interference). In addition, the ~uncommon noise is stuck in the signal loop, and the electromagnetic compatibility test of the electromagnetic device exceeds the specification value. "^ [Summary] The object of the present invention is to provide a system for reducing the frequency of a signal loop to solve problems such as electromagnetic interference.
