Power line communication transmitter with amplifier circuit |
摘要 |
In one embodiment, a transmitter circuit is provided for data transmission from endpoint devices to collector devices over power distribution lines. The transmitter includes an amplifier circuit configured to receive and convert a first data signal to a pulse density modulation (PDM) encoded signal using high frequency pulses that introduce high frequency components. A low-pass filter of the transmitter is configured to filter the high frequency components of the PDM encoded signal to produce a second data signal, which is an amplification of the first data signal. A coupling circuit of the transmitter is configured to communicatively couple the second data signal from the low-pass filter to the power distribution lines. The coupling circuit filters the frequency of the AC and prevents high voltage of the power distribution lines from damaging the transmitter. |
