AL wire DC Reactor

DC reactors, also known as flat wave reactors, are widely used as key components on the DC side of converters, especially in the field of general-purpose inverters. Its core function is to process the AC component in the DC and control it within a preset range to maintain the continuity and stability of the rectified current, reduce current pulsation, optimize the input power factor, and effectively suppress harmonics generated by the converter.

We highlight the following points about its features:

The core design utilizes high-quality cold-rolled silicon steel sheets, a material with low-loss characteristics. The core is evenly divided into small segments by multiple air gaps, which are spaced by epoxy-laminated glass cloth panels coated with a special bonding agent to ensure stable and noise-free air gaps during operation.
For the coil section, we use flat enameled copper wires of class F or H for the winding, which are tightly and uniformly arranged without the need for additional insulation. For small-capacity coils, we use a layer structure, while large-capacity coils are pie-shaped for better heat dissipation.
In the production process, DC reactor coils and cores go through three main steps: pre-drying, vacuum impregnation, and hot baking and curing. We use H-class impregnating varnish for this process. This process allows the coil and core to be tightly bonded, which not only reduces noise during operation but also ensures the stable operation of the reactor in high-temperature environments with a high heat resistance rating.

To ensure the stable performance of the reactor, we have chosen non-magnetic materials for the fasteners of the core column, which helps to reduce the temperature rise of the reactor.
The exposed parts of the reactor are strictly treated against corrosion. Meanwhile, for the lead-in terminals, we have selected tinned copper tube terminals or copper rows to ensure stability and reliability.

This aluminum wire wound DC reactor is suitable for the following scenarios:
1. DC power supply system: used to stabilize the output current of the DC power supply and improve the stability and reliability of the power supply system.
2. Frequency control system: In power electronic equipment such as frequency converter, it is used to filter out high harmonics, reduce electromagnetic interference, and improve system performance.
3. industrial automation field: in all kinds of industrial equipment that need to stabilize DC, this reactor can play an important role, such as electroplating, electrolysis, and welding equipment.
