As a specialized rectifier transformer manufacturer, we design and produce high-current rectifier transformers for electrochemical, aluminum, and other industrial DC power applications. Our rectifier transformers are engineered for high efficiency and reliability.
High Current Expertise
We have extensive expertise in designing and manufacturing high-current rectifier transformers with secondary currents up to Our rectifier transformers are built with secondary currents up to 10,000 A, multi pulse phase shifting for harmonic control, and cooling arranged to the duty cycle. Secondary voltage, vector group and impedance are set to your rectifier topology rather than to a standard table. amperes. Our designs incorporate advanced winding configurations, busbar systems, and cooling methods to handle extreme current requirements efficiently and reliably.
Multi-Pulse Configurations
We offer rectifier transformers in 6-pulse, 12-pulse, 18-pulse, and 24-pulse configurations to minimize harmonic distortion and improve power quality. Our engineering team can recommend the optimal configuration based on your application requirements and power system constraints.
Custom Engineering
Every rectifier transformer application is unique. Our engineering team works closely with customers to design custom rectifier transformers optimized for their specific process requirements, including custom voltage ratios, current ratings, impedance, cooling methods, and integration with rectifier systems.
Applications Experience
We have supplied rectifier transformers for a wide range of applications including aluminum smelting, chlor-alkali production, copper electrorefining, zinc electrowinning, hydrogen production, DC motor drives, and other electrochemical and industrial processes.
Rectifier Transformer Enquiries: the Data We Work From
Rectifier duty is the least standardised product we make, so the quotation turns almost entirely on the information in the enquiry. These are the points that change the design rather than the paperwork:
- Primary voltage, frequency and the permissible system voltage deviation.
- DC output required — voltage and current at the rectifier terminals, including any tap range the process needs.
- Pulse number — 6, 12 or 24 — and whether phase shifting is done inside the transformer or by an external arrangement.
- Rectifier type and the harmonic limits the process or the utility imposes.
- Load profile: continuous, cyclic, or with short overloads, and the ambient conditions at site.
- Cooling method and whether the transformer is installed indoors or outdoors.
- Short-circuit impedance, which sets the fault current the rectifier has to withstand.
Where the process has no previous reference design, we size the transformer from the DC duty backwards — secondary voltage and current, winding arrangement, impedance — and confirm the pulse configuration against the harmonic limits before the winding design is frozen.
