A power distribution network includes a plurality of power source nodes and component nodes, which direct power from the plurality of power source nodes to a plurality of load nodes; a plurality of sensors positioned to sense power flow information for the plurality of power source and component nodes; and a data warehouse housing the power flow information and diagnostic data for the plurality of power source and component nodes. The power distribution network also includes a control system configured to retrieve the power flow information and the diagnostic data; generate stress and health indices and compute a criticality for each of the power source and component nodes; and generate a risk index for each of the power source and component nodes based on their respective stress index, health index, and criticality. The risk index of each node represents the risk the node poses to the power distribution network.

System and method for asset health monitoring using multi-dimensional risk assessment

Electrical current sensing and monitoring methods include connecting sensing a voltage across a conductor having a non-linear resistance such as a fuse element. The current flowing in the conductor is calculated based on at least a first detected state of the sensed voltage and a thermal equilibrium characterization of the conductor.

Electric fuse current sensing systems and monitoring methods

A wireless power transfer circuit can include an input port that can be configured to couple to a power source, an ac excitation circuit having a port coupled to the input port, a resonant circuit coupled to the ac excitation circuit, and a controller circuit that can be configured to operate the ac excitation circuit. The wireless power transfer circuit can operate to inductively transfer power from the resonant circuit and the controller circuit can be configured to change an operating frequency of the ac excitation circuit and change a configuration of the resonant circuit responsive a change in indicated efficiency of the wireless power transfer.

Methods, circuits and articles of manufacture for controlling wireless power transfer responsive to controller circuit states

A system includes an AC input port configured to be coupled to an AC power source, a first AC/DC converter circuit having a first port coupled to the AC input port, and a first resonant circuit coupled to the first port of the first AC/DC converter circuit. The system further includes a second resonant circuit inductively coupled to the first resonant circuit, a second AC/DC converter circuit coupled to the second resonant circuit and a control circuit configured to control the first AC/DC converter circuit responsive to an output of the second AC/DC converter circuit.
