Wound Interphase Reactors for Rectifiers
Interphase reactors represent a fundamental component in AC/DC conversion systems based on multipulse rectifiers such as 6-pulse and 12-pulse ones. These devices play a crucial role in improving power quality on both the AC and DC sides, reducing harmonics and optimizing the overall performance of the conversion system. A properly sized interphase reactor is able to balance the output currents from each converter, consequently improving the performance of the converter itself.
Braga Trasformatori designs and manufactures custom interphase reactors, personalized according to specific application requirements, guaranteeing optimal performance in every operating condition.
The evaluation of the construction method, pass-through or with winding, is made by Braga Trasformatori’s Technical Office based on the specific requirements of the application and also on the dimensional requirements of the Customer.
The main applications are:
- Industrial electrolysis plants
- High power arc furnaces
- Power supply systems for electrochemical processes
- Power rectifiers for metallurgical applications
- High current electric transport systems
- High power DC motor supply
- Special applications where very high DC currents are required
