Harmonics generated by electroplating power supplies mainly originate from the rectification stage and are a significant factor affecting industrial power quality.

By employing **multi-pulse rectification technology and a phase-shifting autotransformer**, active harmonic suppression can be achieved on the power supply side.
Harmonics generated by different rectifier bridges cancel each other out within the system, significantly reducing the harmonic current entering the power grid.

This solution offers the following advantages:

• 1. High-efficiency harmonic mitigation
• 2. High reliability
• 3. High power factor
• 4. Applicable to high-power industrial scenarios

Therefore, in high-power DC power supply applications such as electroplating, electrolysis, and metallurgy, the **phase-shifting autotransformer multi-pulse rectification solution** has become an important technological path for improving power quality and achieving green production.
