Abstract
A method of transmitting data over a power line of a switch mode power supply system includes encoding a switch frequency of the switch mode power supply with the data. A ripple voltage is generated at the encoded switch frequency relative to a voltage generated by the switch mode power supply. The ripple voltage is conducted over the power line of the system. The ripple voltage is de-coupled from the power line and the data is decoded from the encoded switch frequency of the coupled ripple voltage.
