Application: Circuitry and methods for detecting an electrical fault in power conversion circuitry (Patent ID: US20230421053A1)

The patent filed by Rolls-Royce Holdings Plc describes a power conversion circuitry designed to detect electrical faults by monitoring the rate of change of current flowing along different paths within the circuitry. The system includes switching circuitry, current sensors, and control circuitry to detect faults and adjust current flow when necessary. The current sensors are strategically placed along the current paths to measure the rate of change of current, with the control circuitry configured to adjust the fault threshold based on the magnitude of the current measured.

Furthermore, the patent outlines various claims related to the configuration and operation of the power conversion circuitry, including the use of transistors in the switching circuitry, the positioning of current sensors, and the detection of faults based on specific fault thresholds and time durations. The system is versatile, capable of detecting faults in different types of power conversion circuits such as H-Bridge circuits or AC to DC converters. Additionally, the patent includes a method for detecting electrical faults in the power conversion circuitry and a computer-readable medium with instructions to perform the fault detection method when executed on a computer within the circuitry.
