Abstract
The present disclosure provides distributed power and fault management systems. In one example embodiment, a single power transmitter is coupled to a plurality of power receiver devices via a low-ohmic connection. Each power receiver device is configured to provide local power, and to communicate power input information with the transmitter. The transmitter is configured to sum the power input of each receiver and compare the sum to an output power to determine fault conditions that may be present in the system.
Claims21
A distributed power and fault management system, the system comprising:
- a transmitting device to generate power to a plurality of receiving devices, the transmitting device comprising:
- power sensing circuitry to determine a power output to the plurality of receiving devices;
- a controllable switch to control the power output from an input to an output of the transmitting device;
- and
- fault management protection circuitry to determine presence of a fault condition and to control a state of the controllable switch based on the presence of the fault condition;
- the plurality receiving devices coupled to the transmitting device, each receiving device to provide local power to a local load and to communicate, to the transmitting device, data indicative of the local power;
- and
- wherein the fault management protection circuitry of the transmitting device further configured to sum a received local power data from each receiving device and to determine the fault condition by comparing the sum of the received local power data from each receiving device to the output power of the transmitting device.

- primary fault management protection circuitry to determine presence of a fault condition and to control a state of the primary controllable switch based on the presence of the fault condition;
- a first receiver/transmitting pair device coupled to the primary transmitting device, the first receiver/transmitting pair device to determine an input power received from the primary transmitting device and to communicate, to the primary transmitting device, data indicating the input power received from primary transmitting device;
- the first receiver/transmitting pair device comprising:
- a first controllable switch to control a first output power from an input to an output of the first receiver/transmitting pair device;
- and
- first fault management protection circuitry to determine the presence of a fault condition and to control the state of the first controllable switch based on the presence of the fault condition;
- wherein the primary fault management protection circuitry further configured to compare the data, from the first receiver/transmitting pair device, indicating the input power received from primary transmitting device to the primary output power;
- and
- a second receiver/transmitting pair device coupled to the first receiver/transmitting pair device, the second receiver/transmitting pair device to determine an input power received from the first receiver/transmitting pair device and to communicate, to the first receiver/transmitting pair device, data indicating the input power received from the first receiver/transmitting pair device,
- wherein the first fault management protection circuitry further configured to compare the data, from the second receiver/transmitting pair device, indicating the input power received from the first receiver/transmitting pair device to the first output power.
