Application: Protection system and protection method for power converters (Patent ID: US20240204506A1)
The patent filed by BAE Systems Plc describes a protection system and method to prevent damage to components in an inverter module caused by an uncontrolled state of a permanent magnet (PM) electric machine. The system includes a back-up power supply, gate driver circuitry, semiconductor switches, and a control module. The back-up power supply receives input from a DC bus and provides power to the gate driver circuitry, which controls the semiconductor switches connected to the PM electric machine. The control module monitors the voltage of the DC bus and triggers the gate driver circuitry to short respective phases when a specific threshold is met, preventing damage to the components.
The system comprises multiple claims detailing the configuration and operation of the protection system. It includes provisions for a second power supply, control module functionalities, response to varying voltage thresholds, and integration within a vehicle system. The claims also address scenarios such as power backup during vehicle towing, communication interfaces with other controllers, and the use of comparators and filters for efficient operation. Additionally, the patent outlines the coordination of multiple inverter modules connected to the same PM electric machine, ensuring synchronized protection measures across the system. Overall, the patent aims to safeguard components in an inverter module from potential damage due to an uncontrolled state of the PM electric machine, enhancing the reliability and safety of the system.
