BDH High-Voltage VFD
Product Overview
The BDH Series represents a mature, high-performance High-Voltage Variable Frequency Drive engineered for demanding industrial motor control applications. Built on a modular cascaded H-bridge architecture, this series delivers direct high-voltage output without requiring output step-up transformers.
Utilizing advanced multi-pulse phase-shifting rectification technology, the BDH series effectively eliminates input-side harmonic distortion, ensuring grid-compliant operation that exceeds international power quality standards. Suitable for metallurgy, cement production, oil & gas, and large-scale mining applications, the BDH series provides stable, energy-efficient solutions for driving asynchronous, synchronous, and permanent magnet motors in challenging environments.
