Application: Method of monitoring a health state of a power semiconductor device (Patent ID: US20240192263A1)
The patent filed by Rolls-Royce Holdings Plc describes a method for monitoring the health state of a power semiconductor device by analyzing parameters related to transient voltage, transient current, and energy during turn-on and operation. The health state is determined based on comparing initial and operating energy parameters. If the operating energy parameter exceeds a threshold, the device is considered aged. The method also involves normalizing energy parameters based on load parameters and integrating current and voltage parameters digitally.
Additionally, the patent includes claims for an external circuit to connect to the power semiconductor device, comprising components such as a rogowski coil for measuring transient current, an analog isolator connected to a voltage sensor, a processor to perform the monitoring method, a gate driver for voltage and current monitoring initiation, and a field-programmable gate array for signal integration. The circuit may also include temperature sensors to monitor the device's temperature and provide data to the processor for analysis. The patent aims to provide a comprehensive system for monitoring and assessing the health state of power semiconductor devices to ensure optimal performance and longevity.
