Formed foil is the essential core material inside aluminum electrolytic capacitors, directly determining the performance of high-end electronics. Driven by rapid growth in 5G, electric vehicles, and AI computing, demand for premium foil is surging. In Xinjiang, China, advanced foil production requires ultra-stable power, where even minor voltage fluctuations can compromise quality. Delta stepped in with an innovative power solution to ensure high-yield, uninterrupted production.
Can Legacy Power Support Modern Manufacturing?
A leading formed foil manufacturer in Xinjiang is upgrading production lines, encountering strict power challenges. The new forming tanks involve low voltage and high current applications that require adjustable direct current from tens to hundreds of volts. Traditional transformers and rectifiers fail to meet these demands, causing high output ripple, poor uniformity, slow switching, and massive energy losses. To resolve this, Delta introduced the Solid State Transformer (SST). With its flexible voltage adjustment, the SST precisely satisfies these complex direct current requirements, eliminating power bottlenecks and ensuring premium product quality.
Delta provides an innovative, high-efficiency power solution for formed foil production, enabling process upgrades and superior product quality.
Architectural Breakthrough: Delta SST
To address production stability and rising electricity costs, Delta delivered a customized SST turnkey solution. By deploying five systems with a total capacity exceeding 5.4 MW, Delta replaces conventional multistage equipment, directly converting medium-voltage AC grid power into multi-level DC output.
Three Core Advantages Unlocking High-End Potential
Delta SST overcomes conventional manufacturing limits through three decisive benefits:
- Superior Uniformity: Silicon Carbide (SiC) high-frequency conversion delivers ultra-low ripple and millisecond-level dynamic response, shielding the process from power fluctuations to maximize foil consistency and yield.
- Significant Energy Savings: Proprietary solid insulation and high-efficiency SiC technology achieve up to 98.5% conversion efficiency, cutting power losses by over 30% and delivering major electricity savings across the equipment lifecycle.
- Flexible Line Switching: Smart power controls and multi-voltage outputs allow rapid adaptation to diverse product specs, eliminating long recalibration downtimes.
The success of Delta SST in Xinjiang proves that this architectural innovation extends well beyond data centers into advanced industrial manufacturing. Moving forward, Delta will continue providing high-efficiency solutions to help global industries achieve higher yields, lower costs, and sustainable growth.
