AI Technical Summary

Technical Problem

Existing power distribution systems, particularly those used in remote RF radios and 5G cellular networking, face challenges such as high costs, longer turnaround times for permitting, and inefficiencies due to power limitations and infrastructure constraints.

Method used

A fault-responsive power system utilizing asynchronous load current switching, which includes a supply-side current sensor, a supply-side switch, a remote-side switch, a pulse generator, and a fault management controller to manage power delivery and reduce currents when thresholds are exceeded.

Benefits of technology

The system effectively manages faults without synchronization between supply-side and remote-side components, reducing power consumption and costs, and enhancing safety and scalability for mass deployment.

Abstract

A fault-responsive power system and method using asynchronous load current switching. A first supply-side current that flows from a power supply into a first conductor, which electrically couples the power supply to a load, is measured. Power is delivered to the load by modulating a first remote-side current on and off, with the remote-side current entering the load from the first conductor. Once it is determined that the first supply-side current has met or exceeded a magnitude threshold for at least a duration threshold, the first supply-side current is reduced such that the first supply-side current is less than the magnitude threshold. A data signal may also be transmitted by embedding a data signal in the first remote-side current through the modulation of the first remote-side current, and demodulating the data signal in the first supply-side current.
