Overview
1. To effectively reduce harmonics injected into the grid from the load side and improve power quality, our company provides multi-pulse phase-shifting rectifier transformers. We can customize single-unit 12-pulse, 24-pulse, 36-pulse, dual-unit 24-pulse, and o ther combinations of phase-shifting rectifier transformers according to requirements.
2. The main characteristic of rectifier transformers is the presence of unidirectional pulsating current in the windings, with the sec ondary current being a non-sinusoidal AC waveform. Our company's rectifier transformers use ANSYS simulation technology for multi-physics field coupling simulation, optimizing winding electromagnetic wire specifications and cooling air ducts, effectively reducing eddy current losses caused by harmonic currents of various frequencies, lowering product operating temperature, and enhancing product overload capacity.
3. The transformer core uses high-quality cold-rolled silicon steel sheets from Baowu Group, cut and stacked using a seven-step 45° fully mitered joint process. No-load losses, no-load current, and operating noise are all superior to national and industry standards, effectively reducing product weight, dimensions, and greatly reducing transformer inrush current during closing.
4. The transformer enclosure is made of 2.0mm cold-rolled steel plate, with high-temperature silicone rubber strips sealing between the frame and movable panels, meeting protection class requirements while effectively reducing vibration noise. The enclosure meets C5M anticorrosion standards, with corrosion resistance, weather resistance, and UV resistance. The coating is crack-resistant and wear-resistant.
5. The transformers can adapt to large instantaneous loads and precisely match subsequent rectification elements and filtering devices to ensure output current stability and efficiency.
6. The transformer can be equipped with intelligent components to monitor its operating status in real-time, including real-time power transmission, operating voltage and current, operating temperature, insulation performance monitoring, etc. When any performance parameter is abnormal, it can output a switch alarm signal. It has a "black box" function, allowing all operating parameters to be viewed in
real-time on the cloud.

Applications:
Rectifier transformers are indispensable components in power electronic systems, acting as bridges connecting AC and DC power forms. With the rapid development of industry and transportation, the demand for rectification equipment is growing. Meanwhile, the large amount of harmonics generated by rectification systems severely pollutes the power grid. Multi-pulse phase-shifting rectifier transformers are widely used in high-power industries and places with requirements on grid-side harmonic currents, such as chemical, metallurgy, coal, cement, rolling mills (steel plants), and rail transit. Rectifier transformers with bidirectional transmission function are also widely used in ne w energy fields like energy storage.
