| 摘要 |
The present disclosure provides techniques for power factor correction on a constant current system and also provides power line communications on the same power factor correction circuit. In one example embodiment, through controlled charging and draining of an input capacitor, the power factor correction circuit generates an input voltage which is in phase with the input current. Communication data is also embedded in the input voltage and/or input current by further charging and draining of the input capacitor according to a controlled switching scheme which includes both input current phase data and corresponding communication signals. |
