A deflection lever decouples lever travel from contact-free signaling, enabling clear switch position detection in tight steering column space.
- WBG Power Switch Self-Diagnostics for Early Fault Isolation
Integrated gate-driver diagnostics monitor WBG switch electrical characteristics to detect degradation early and disable operation before damage.
- Gate Drive Circuit Topology for Surge Voltage and Miller Period Control
Parallel RC gate paths shape transistor switching to limit surge voltage and shorten the Miller period in semiconductor breakers.
- Resonant Power Converter Switching to Limit EMI Noise
A bidirectional switch and limiter control voltage slew rate in a resonant power converter, cutting radiation noise during soft switching.
- MOSFET Electronic Fuse Circuit for Fast Abnormal Power Cutoff
A sampled-voltage MOSFET fuse circuit cuts abnormal in-vehicle power quickly, protecting loads from vibration-driven contact faults.
- Relay-Capacitor Multiplexer for High-Voltage IRE Pulse Switching
Parallel relays and capacitors form a multiplexer that switches 2 kV+ IRE pulses across electrodes without costly high-rated switches.
- Bidirectional Circuit Breaker Layout for Low-Loss Ground Fault Detection
Two feed-side IGBT switches cut DC forward losses while enabling ground fault identification and location in the network.
