PLC Development Board

The key components are circled in the following schematic.

Figure 4-9. Transmit Filter, Transmit Amplifier, and Receive Filter

4.3.7

High Voltage Coupling Circuit

This circuit couples the signal from the board on to the powerline. On the receive side, the same
circuit couples the carrier on the powerline into the board, while rejecting the actual 50-Hz and 60-Hz
power. The isolation transformer in the circuit is required for safety.

Table 4-5. Key Transmit and Receive Components

The key components are circled in the following figure.

Component

Description

T1

This is the isolation transformer that isolates the HV and LV sections of the board. It has a 1:1
turns ratio.

C9

This is the coupling capacitor that couples the communication signal to the powerline and
rejects low frequency noise. The voltage rating and X1/X2 safety ratings of this component
are important parameters.
