Passing through the power factor improvement circuit has the advantage that the power factor improvement effect does not fall, which makes it possible to efficiently consume power and save energy.
  • the power line communication method of the indoor DC power system uses a DC power line communication method that modulates and demodulates a control signal of several to several tens of kilohertz to a DC voltage. Since it can be attenuated, the control signal can be extracted with less attenuation while reducing the power loss generated in the existing AC power line communication circuit. Therefore, power consumption can be reduced without adding another circuit in the existing power line communication circuit.
  • the power line communication method of the indoor DC power system by using a pulse width modulation method or a pulse period modulation method, the entire power transmission section in which the power and data supplied for driving the load is transmitted to the power transmission section and the By dividing the data into the data transmission section, the data signal is transmitted in the section where the power is cut off or "Low", so that not only does not change the average power supplied to the load side but also increases the voltage level of the data signal, The transmission error of the signal can be reduced.
  • the power line communication method of the indoor DC power system according to the present invention can be controlled by varying the power supplied to the load using a pulse width modulation method or a pulse period modulation method, the switching frequency of the pulse modulation method is several tens of KHz. As it is high, it can be applied to the field that needs real time control such as motor control system because it can have a faster data transmission cycle because the data transmission section is repeated faster than the existing method. In addition, since power and data signals may be transmitted using a pulse width or a pulse period modulation method, a synchronization process may be very easy when transmitting and receiving data signals.
  • the present invention improves the power factor control efficiency for indoor electrical appliances by configuring indoor wiring as a DC power system, and transmits control signals while preventing power loss when controlling and transmitting external control signals to indoor electrical equipment using a power line communication method. It can be used for indoor DC power system and its power line communication method which can improve the effect.

Abstract

La présente invention concerne un système d'alimentation électrique à courant continu pour espace intérieur et un procédé correspondant de communication sur ligne d'alimentation. Un système d'alimentation connecté à une ligne d'alimentation à courant alternatif selon la présente invention comprend : une unité intégrée de circuit redresseur convertissant en tension continue le courant alternatif fourni pour une zone prédéterminée par la ligne d'alimentation à courant alternatif, une unité intégrée de circuit de correction du facteur de puissance connectée à une sortie de l'unité intégrée de circuit redresseur de façon à intégrer et corriger les facteurs de puissance d'une charge, une ligne d'alimentation continue connectée au circuit de correction du facteur de puissance et à toutes les prises électriques et bornes de prélèvement d'électricité, et un système intégré de communication sur ligne d'alimentation réalisant une communication sur ligne d'alimentation à courant continu au moyen de ladite ligne d'alimentation électrique à courant continu. Comme indiqué ci-dessus, le câblage de l'espace intérieur est réalisé selon un système d'alimentation électrique à courant continu de façon à améliorer l'efficacité de la commande de facteur de puissance sur les appareils électriques intérieurs. Les pertes de puissance sont évitées et les effets de la transmission de signaux de commande sont améliorés lorsque des signaux de commande d'une source extérieure sont émis ou reçus par des appareils électriques intérieurs par l'intermédiaire de la communication sur ligne d'alimentation dans le but de commander les appareils électriques intérieurs.
