A charging and communication system includes a potential output terminal for supplying power to a to-be-charged device; a first controller for generating a first control signal; and a first potential switching module for switching a first potential and a second in response to the first control signal. At least one of the first potential and the second potential is a charging potential, so as to supply power to the to-be-charged device. The first potential and the second potential are not equal, so as to communicate information to the to-be-charged device. The complexity of the hardware circuit structure is reduced. The stability and reliability of the circuit structure is improved.

A method and system for bidirectional data, power transmission, electrical/electronic fault isolation, and system recovery is shown and described. An exemplary embodiment includes a DC power source, a main power controller (MPC) with a MPC microprocessor and an MPC power switcher driver and fault switching control circuit, and a plurality of Nodes connected to the DC power source through conductors that allow both power to be supplied and bidirectional data transfer between a data receiver and the plurality of Nodes. The fault switching control circuit can provide for short detection and isolation (or other fault detection and isolation) without the direct involvement of the MPC microcontroller. The combined use of the conductors for power, data transmission, and fault detection and isolation offers significant advantages over the prior art in terms of weight reduction, system modularity, and complexity, as well as system protection and survivability.

A load control system includes a controller that modifies an alternating current (AC) signal at a controller input to provide, on a cycle-by-cycle basis, an encoded AC signal that exhibits a unique AC signature at a controller output. The unique AC signature is associated with a particular user-selectable load characteristic. The load control system also includes a load circuit that receives the encoded AC signal. The load circuit includes a decoder that decodes the encoded AC signal to determine the unique AC signature of the encoded AC signal. In response to determining the unique AC signature of the encoded AC signal, the load circuit changes a load characteristic of the load circuit to exhibit the particular user-selectable load characteristic associated with the unique AC signature.
