Four-Quadrant Phase-Shifting Rectifier Transformer
BBELC’s Four Quadrant Phase Shifting Rectifier Transformer is designed for bidirectional power conversion in advanced VFD systems, enabling motor drive, regenerative braking, and energy recovery.
Product Introduction
Four-Quadrant Phase-Shifting Rectifier Transformer
BBELC’s Four Quadrant Phase Shifting Rectifier Transformer is a specialized dry type transformer designed for medium voltage VFD systems with bidirectional power conversion requirements. Through multi-winding phase-shifting technology, it provides stable power conversion for rectifier systems while enabling regenerative braking and energy recovery between the motor and grid. Designed for high-performance industrial drives, it helps improve energy efficiency, reduce harmonic distortion, and ensure reliable operation in demanding applications such as mine hoists, cranes, elevators, and heavy-duty drive systems.
- Rated Voltage: up to 10KV
- Rated Power: up to 21MVA
- Insulation Class: F/H
- Standard: IEC/IEEE
