Product Overview

The rectifier transformer is a special type of transformer primarily used to convert alternating current (AC) into direct current (DC). It is widely applied in power electronics, DC power supply systems, and industrial equipment, particularly in applications requiring efficient rectification.


Key Features

1. High Efficiency Rectification: The rectifier transformer is designed for optimal performance, enabling efficient conversion from AC to DC while minimizing energy loss.

2. Special Winding Configuration: It typically employs tapped windings to ensure that the required voltage and current are provided during the rectification process, meeting load demands.

3. Good Electrical Insulation: The rectifier transformer features excellent electrical insulation properties, ensuring safety under high voltage and high current operating conditions.

4. Strong Adaptability: It can adapt to various working environments and load requirements, making it particularly suitable for heavy and fluctuating loads.

5. Easy Maintenance: The design considers ease of maintenance, resulting in lower complexity for routine inspections and repairs, which reduces operational costs.


Application Areas

· Power Electronics Devices: Widely used in inverters, DC speed controllers, and other power electronic devices.

· Electrolytic Industry: Provides the necessary DC power in processes such as aluminum electrolysis and chlor-alkali production.

· Electric Vehicle Charging Stations: Supplies stable DC power for electric vehicle charging systems.

· Rail Transit: Delivers DC power in urban rail transit and high-speed rail supply systems.


Technical Parameters

· Rated Voltage: Customizable according to customer requirements, suitable for various voltage levels.

· Capacity Range: Rated power from tens of kilovolt-amperes (kVA) to several thousand kilovolt-amperes (kVA), meeting the needs of various applications.

· Cooling Methods: natural cooling (ONAN).


Conclusion

With its high efficiency and reliability, the rectifier transformer is an indispensable device in power electronics and DC power supply systems. Our company offers a variety of specifications for rectifier transformers to meet customer needs in various applications, ensuring safe and stable operation of equipment.
