Project Background & Selection
Trusted by Leading Research Institutions
In 2025, the Institute of Plasma Physics, Chinese Academy of Sciences initiated a critical procurement project for their PSM (Pulse Step Modulator) power supply system. Facing complex technical requirements for electrical isolation and harmonic suppression, the Institute conducted a comprehensive and rigorous screening of potential suppliers.
yingbeg was ultimately chosen as the sole R&D and manufacturing partner for this customized specialized transformer. This selection validates our ability to handle specialized, high-specification orders that standard manufacturers cannot fulfill. We successfully delivered a solution that balances complex multi-winding architecture with reliable performance.

Design & Engineering Details
Multi-Winding Isolation Technology
As seen in the product image, the transformer utilizes a complex arrangement of high-voltage bushings (Yellow, Green, Red phases). This corresponds to the internal 18 Star (Y) and 18 Delta (Δ) secondary windings. This design is not for general distribution but is specifically engineered to provide isolated power channels for sensitive scientific equipment, preventing interference between modules.
Robust Construction
The unit features a robust epoxy resin casting process (visible in the red coils), ensuring resistance to moisture and mechanical stress. The base includes a dedicated control box for temperature monitoring and fan operation, ensuring the unit remains within safe operating limits during continuous research operations.
Need a Specialized Transformer Solution
Like the project for the Institute of Plasma Physics, Chinese Academy of Sciences, your application may require more than just a standard catalog product. At yingbeg, we specialize in translating complex technical requirements into reliable, custom-manufactured power solutions.
