An apparatus comprising a signal transformer coupled to a power line and a signal transmission, reception, or detection circuit. A sensor is configured to be responsive to the power line current or magnetic flux generated in a ferrite core of the signal transformer. When the sensor indicates that the flux generated by the power line current mat cause an attenuation of the signal strength, a second circuit generates a current through a flux cancelling winding that cancels at least some of the flux generated by the power line current.

Magnetic flux cancellation for power line communications

Various implementations described herein are directed to determining an order of power devices connected in a serial string to a central power device. The physical order may be stored in a non-volatile computer-readable storage medium.

Apparatus and method for determining an order of power devices in power generation systems

Various implementations described herein are directed to a method for determining an order of power devices connected in a serial string. A command is transmitted, to at least one first power device of a plurality of power devices, to change an output electrical parameter. At least one electrical signal is caused to be transmitted from at least one second power device of the plurality of power devices. At least one measured value responsive to the electrical signal is received from at least one of the plurality of power devices. A determination is made, by analyzing the at least one measured value, which ones of the plurality of power devices are ordered in the serial string between the at least one first power device and the at least one second power device.
