Power line communication ac/dc adaptor

A power line communication (PLC) AC/DC adaptor, comprising:

• a filter comprising a differential mode choke and a common mode choke, the filter coupled to AC to receive a PLC signal;
• a rectifier coupled to the filter;
• a power factor correction circuitry coupled to the rectifier;
• a transformer module comprising a primary side and a secondary side, wherein the primary side is coupled to an output of the power factor correction circuitry, the secondary side comprises a controller;
• and
• a PLC module coupled to AC to receive the PLC signal and coupled to the secondary side of the transformer module;
• wherein the PLC signal is processed by the PLC module, the PLC module outputs a first control signal to the secondary side of the transformer module;
• wherein the PLC signal is processed by the filter, the rectifier, and the power factor correction circuitry in that order, the power factor correction circuitry outputs a power signal to the primary side of the transformer module;
• wherein the first control signal is processed by the controller, the controller outputs a second control signal, the transformer module outputs the power signal and the second control signal.
