Current Controllers TRIZ Cases
- BLDC Commutation Phase Tuning Using Current Feedback
Current-driven adaptive commutation tuning helps BLDC motors maintain efficiency and consistent control under changing load and speed conditions.
- Back-EMF Zero-Crossing Circuit for Motor Position Offset Calibration
Comparator-based back-EMF zero-crossing detection calibrates BLDC motor position offset, improving sensor alignment and control accuracy.
- Sensorless Reverse Rotation Detection in De-Energized Electric Machines
Remote waveform analysis detects reverse rotation and estimates speed in de-energized electric machines without installed sensors.
- Induction Machine Rotor Angle Determination Without Sensors
Integrating measuring voltage pulses into the modulation unit minimizes voltage and current fluctuations while determining rotor angle without sensors.
- Dynamic Mask Time Adjustment for Motor Noise Suppression
Dynamic mask time adjustment resolves the trade-off between noise suppression and control response speed by adapting mask duration to operating conditions.
- Motor Drive Control Resonance Suppression via Timing Adjustment
Controller adjusts energization switching timing to reduce motor resonance, avoiding costly high-processing microcomputers.
- Motor Drive Sampling Adjustment for Current Detection Consistency
A sampling adjustment unit modifies A/D converter timing to stabilize current detection values across varying detector response speeds.
