DESIGN OF A POWER LINE COUPLER AND A POWER LINE COUPLER DESIGNED THEREOF

摘要

The present invention relates to a power line coupler design method comprising a transmitter, a receiver, and a power line combiner circuit for processing a signal transmission / reception between a power line and a power line modem, the method comprising: a transmission equivalent circuit including a magnetization inductance Determining a power line impedance of the power line as a minimum value at which a signal attenuation due to a cut-off frequency occurs with respect to the transmission equivalent circuit; and calculating a maximum output voltage and a maximum Comprising the steps of: determining a current limiting resistor that limits the amplifier current of the transmitter based on an output current; and determining a current limiting resistor for limiting the amplifier current of the transmitter based on the output current, Lt; RTI ID = 0.0 capacitor / RTI And a power line coupler designed by the method.
