Abstract
A controller connected to a line voltage, includes an auto-transformer that provides a nominal line voltage at a first end terminal and a signaling voltage at a transformer tap. A first switch has a first switch terminal connected to the first end terminal of the auto-transformer, and a second switch terminal connected to an output node of the controller. A second switch has a first switch terminal connected to the transformer tap of the auto-transformer, and a second switch terminal connected to the output node. A switch controller is configured to output first and second switch signals responsive to a control signal, to control the first and second switches to insert signaling transitions onto the line voltage by selectively connecting the nominal line voltage at the first end terminal and the signaling voltage at the transformer tap to the output node.
