Pulse width control replaces a mechanical switch for vehicle headlamp leveling, cutting cost while preserving angle adjustment and visibility.
A shared-switch transformer circuit replaces the H-bridge to deliver bipolar inductive-load current with lower noise, losses, and short-circuit risk.
PWM-based motor feedback adjusts vehicle headlamp angle without a mechanical switch, cutting cost while improving visibility and convenience.
Load-triggered forward and reverse rotation with cumulative angle control helps root canal tools avoid fracture without sacrificing cutting efficiency.
