- Motor Controller Fault Detection Circuit for Fast Accurate Tripping
Combining DESAT, overcurrent, and transient trip signals enables faster, more consistent motor controller fault interruption.
- Motor Controller Fault Detection Circuit With Merged Trip Signals
By merging DESAT, OCD, and transient trip signals, this circuit speeds solid-state motor fault interruption while avoiding inrush-triggered trips.
- Power Distribution Unit Fuse Triggering for High-Current Shutdown
A dual-trigger path uses a microcontroller and shunt amplifier to open contactors and fire active fuses within I2t limits.
- Aircraft Electrical Network Reconfiguration via Distributed State Tables
Distributed protection units use location-based tables and shared state data to reconfigure aircraft electrical networks with less wiring.
- Voltage Detection Circuit With Switched Reference Thresholds
Multiple reference voltage sets and latch-based switching improve voltage drop detection accuracy and help prevent circuit failure.
- Counter-Based e-Fuse Protection for Circuit Overcurrent Reliability
A counter-based e-Fuse updates accumulated current damage over time to cut false triggering and protect lower-spec circuit elements.
- Remote Leakage Protection Relay for Safe Power Disconnection
An independent relay and communication module enable remote power control while preserving reliable leakage fault disconnection and state monitoring.
