Single-Phase Induction Motor Starters TRIZ Cases
- Pincer-Type Phase Inverter Device for Motor Reversal
Integrating phase inversion with cut-off functions reduces component count while maintaining short-circuit current resistance.
- AC Motor Inverter Control for Torque Pulsation Reduction
Variable harmonic voltage phase control reduces torque pulsation by suppressing even-ordered harmonic currents while maintaining half-wave symmetry.
- Fan Motor Driving Circuit Soft Switching for Coil Current Strain
A fan motor driving circuit varies H-bridge duty ratios to suppress coil current strain and reduce noise.
- Induction Motor Inductance Estimation Without Speed Sensors
Estimating induction motor inductance parameters using instantaneous reactive power and nameplate data.
- Mid-Voltage Rectifier Harmonic Distortion Compensation
The control method minimizes dead zone effects by optimizing phase angle differences between grid-side current and voltage to reduce low-order harmonic distortion.
- Adaptive Harmonic Mitigation in Power Converters
Switching angle generator computes rectifier angles to control harmonic components, reducing total harmonic distortion without hardware filters.
