Abstract
A fault protection system and method of fault protection for permanent magnet machine (PMM)-based systems that utilize machine neutral decoupling (MND) to shut down a shorted winding and/or to isolate a short-circuit fault to prevent damage to a permanent magnet machine and to any downstream components are provided. The invention may be used for high-reactance and/or high current PMM-based systems, such as are commonly found in industrial and aviation applications.
