System and method for data transmission over a power line of a switch mode power supply by frequency modulating the switch frequency thereof
A method of transmitting data over a power line of a switch mode power supply system comprises the steps of: encoding a switch frequency of the switch mode power supply with the data; generating a ripple voltage at the encoded switch frequency by the switch mode power supply; conducting the generate...

| Zusammenfassung: | A method of transmitting data over a power line of a switch mode power supply system comprises the steps of: encoding a switch frequency of the switch mode power supply with the data; generating a ripple voltage at the encoded switch frequency by the switch mode power supply; conducting the generated ripple voltage over the power line of the system; coupling the ripple voltage from the power line; and decoding the data from the encoded switch frequency of the coupled ripple voltage. |
