Abstract:
A power line communication device includes a DC power source device, a power line, and a master station that modulates a supply voltage VBUS supplied to the power line according to transmission data to be transmitted. The master station includes a modulation capacitor that is precharged with a modulation amplitude voltage, a polarity switch unit that determines a polarity of the modulation capacitor connected to the power line according to transmission data, and an inductor connected between the DC power source device and the power line.
