Abstract
A power line communication (PLC) AC/DC adaptor includes a filter, a rectifier, a power factor correction circuitry, and a PLC module. The filter includes a differential mode choke and a common mode choke. The differential mode choke is coupled to AC. The common mode choke is coupled to the differential mode choke. The rectifier is coupled to the common mode choke. The power factor correction circuitry is coupled to the rectifier. The PLC module is coupled to AC to process a PLC signal from AC and output a control signal.
Claims16
A power line communication (PLC) AC/DC adaptor, comprising:
- a filter, the filter comprising a differential mode choke and a common mode choke, an input of the differential mode choke being coupled to a power line carrying a PLC signal and an alternating current to block the PLC signal, and an output of the differential mode choke being coupled to the common mode choke;
- a rectifier coupled to an output of the common mode choke;
- a power factor correction circuitry coupled to the rectifier;
- a transformer module, the 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, and the secondary side outputs a power signal;
- and
- a PLC module coupled to the power line and the differential mode choke to receive the PLC signal from the differential mode choke, the PLC module processing the PLC signal and outputting a first control signal.
