| Zusammenfassung: | According to the present invention, a DC power line communication method is a method of supplying power from a DC power source to a DC load via a power line and communicating information. The method includes the steps of: receiving and processing information to be communicated; transmitting output power while switching the polarity of the output power of the DC power source according to the information; receiving the output power of which polarity is switched; extracting information from a pattern in which the polarity of the received output power is switched; and controlling the DC load using the extracted information. The present invention provides the DC power line communication method, which is strong against external noise, and the DC power line communication method can be implemented economically.
