- PWM Motor Braking Circuit for Power-Loss Heat Control
PWM braking uses motor-induced voltage after power loss to stop rotation while shifting heat dissipation away from the PCB.
- Fan Brake Circuit for Fast Stop Without Airflow Blockage
Stored energy briefly shorts the motor at power-off to stop fan inertia fast, then releases braking so airflow-driven cooling can continue.
- Power Tool Regenerative Braking Profiles for Battery Pack Capacity
Battery pack ID sets a braking profile that recovers motor braking energy while limiting recharge current that could damage battery components.
- Hybrid Brake Switch Layout for SIL3 Elevator Brake Monitoring
A reordered semiconductor and electromechanical switch layout enables SIL3 elevator brake monitoring with less test circuitry and lower hardware burden.
- Hybrid Safe Brake Switching for SIL3 Elevator Control
