Narrow-band PLC modem
Skala, Milan ; Krajsa, Ondřej (referee) ; Mišurec, Jiří (advisor)
This bachelor's thesis deals with narrow band PLC modem for 230/400 V power line. In the first chapter we can find basic theory about using modulation, interference, impedance of line, communication, capacitive and inductive coupler. Next chapter deals with design and simulation of capacitive coupler, transceiver circuit, receiver circuit, power supply and circuit for modem synchronization with power line frequency. In this chapter we can find information about building a converter from UART to USB. Third chapter of this thesis is dedicated to designing the printed circuit board and building the modem. Last chapter deals with setting the modem switches, description of its inputs and outputs and basic manual for the modem's software.
