Claim:
1. A power factor correction circuit with power line communications, comprising: an input capacitor configured to receive an input current from a constant current source and produce an input voltage, the input capacitor to be coupled in a parallel configuration with the constant current source; a switching device coupled to the input capacitor, wherein the switching device switches between an OFF state and an ON state, and wherein the input voltage rises when the switching device is in the OFF state and drops when the switching device is in the ON state; and a controller coupled to the switching device, wherein the controller controls switching of the switching device between the OFF state and the ON state, and the switching of the switching device shapes the input voltage to be in phase with the input current, and wherein the switching of the switching device generates disturbances on the input voltage and the input current, the disturbances having communication data.
