ABSTRACT: Telecom sectors generally
operate at negative voltages to reduce the effect of corrosion caused in the
metallic wire due to electrochemical reaction while communicating signals. To
feed those lines and to have an effective digital data transmission, a power
electronic converter referred as Modified Negative Luo Converter (MNLC) is
proposed in this paper. MNLC is a high gain converter in which the output
voltage increases in geometric progression. This paper portrays a novel concept
of a 50 Hz pulse data transmission throughRLCG
(Resistance-inductance-capacitance with a shunt conductance) transmission line
using MNLC. Signal frequency of 50 Hz to be transmitted is anded with a high
frequency pulse that charges and discharges MNLC and produces the boosted
negative output voltage. The boosted output is again transmitted through the
RLCG transmission line from which 50 Hz data pulse is retrieved at the output
of the transmission line by comparing with a comparator signal. This sort of
MNLC aided data transmission not only introduces less loss in its transmitted
data but also overcomes various health hazards of conventional radio frequency
(RF) communication. This technique also proves that any data bit stream can be
transmitted and retrieved using the proposed high gain DC-DC converter. The
simulation model of the proposed system is implemented in MATLAB for various
switching frequencies with its prototype of the converter developed and the
results are verified.
