Publication number: 20220294491Abstract: Instead of the method of performing the power disconnection in the existing phase angle control AC power line communication, using relays or various power semiconductor devices, if communication is executed through data mapping on a pattern where polarity switching (in the case of AC, phase-shifting by 180°) occurs at a differential voltage level of a power line, no power disconnection occurs and high voltage interval is utilized so that the power line communication is strongly resistant to external noise and provides high communication speed, while transmitting several bits in one period of AC voltage waveform. This solves the disadvantages the existing classical condenser coupling type power line communication and the phase angle control AC power line communication for long distance have had. Even though the power line communication is utilized for DC power line communication, many advantages are obtained and high power transmission efficiency is achieved through the relays.Type: ApplicationFiled: August 10, 2020Publication date: September 15, 2022Inventors: Jae Boo CHOI, Changjoon CHOI
