High Reliability · Domestic Innovation | Shanghai Yongming Brings AI Server Capacitor Solutions to the 29th Academic Annual Meeting of China Power Supply Society: AI Server Edition

Shanghai Yongming Electronics will participate in the 5th China Power Electronics and Energy Conversion Conference & Exhibition (CPEEC) — also serving as the 29th Academic Annual Meeting of the China Power Supply Society — from November 6 to 7, 2026. You can find us at Booth D21, Hall B1, at the Suzhou International Expo Center.

We will showcase a comprehensive range of capacitor solutions tailored for five key sectors: new energy power generation and energy storage, electrified transportation, AI servers, robotics and motor drives, and power device components. Notably, we will feature a dedicated zone for AI servers, offering a full-chain selection of capacitors—ranging from supercapacitors to electrolytic capacitors. We cordially invite you to visit our booth for an in-person discussion.

PART 01: Comprehensive Capacitor Solutions for AI Servers

The explosive growth in AI computing power has created unprecedented challenges regarding power conversion efficiency, motherboard power supply stability, and power-loss protection (PLP) for servers. Yongming’s capacitor solutions cover four critical areas within AI servers—backup power systems, main power supply units, motherboards, and storage—providing a robust, end-to-end foundation for AI computing infrastructure.

1) AI Server Backup Power (BBU/CBU, RAID Cards, and Storage Backup Power)

To address the need for transient voltage regulation and space constraints during sudden power outages, Yongming offers two types of supercapacitor solutions, ensuring system stability and data integrity under extreme conditions:

Solution 1: Hybrid Supercapacitors (for AI Server BBU/CBU)

Yongming’s SLF series of hybrid supercapacitors provides a powerful solution for managing transient voltage fluctuations and space limitations during unexpected power loss.

Key Advantages:

Transient Voltage Regulation: With an internal resistance as low as 0.8mΩ, these capacitors deliver rapid response to voltage fluctuations under high-current conditions. Compact, Lightweight, and Ultra-Fast Charging: While maintaining high reliability, this design achieves a 50%–70% reduction in volume and a 50%–60% decrease in weight, alongside a 5-fold increase in charging speed—effectively overcoming space constraints. Exceptional Longevity: Supports a cycle life of 1 million cycles, with an operating temperature range of −30°C to +70°C.

Option 2: Electric Double-Layer Supercapacitors (Backup Power for RAID Cards)

For RAID card backup power requirements, we offer electric double-layer capacitors (EDLCs) characterized by low internal resistance, long lifespan, a compact form factor, and high energy density. These capacitors support an operating temperature range of −40°C to +70°C.

Option 3: Electric Double-Layer Supercapacitors (Backup Power for Server Storage and Edge Computing)

To address the need for data protection during power loss in server storage drives (such as SSDs), we offer the SDN series of standard products, providing long-life, highly reliable backup power support.

2) AI Server Power Supplies

As AI server power supplies increasingly evolve toward higher frequencies and higher power densities—driven by the adoption of SiC/GaN technologies—Yongming offers a comprehensive capacitor portfolio covering everything from the PFC input stage to the point-of-load (POL) output stage:

3) AI Server Motherboards

Solution 1: Stacked Polymer Solid Aluminum Electrolytic Capacitors

During AI server operation, instantaneous power consumption around the chips fluctuates sharply. Voltage instability can directly lead to a loss in computing performance or even system restarts. Yongming’s low-ESR stacked capacitors (with ESR as low as 3mΩ) are positioned in close proximity to the CPU/GPU, enabling rapid response to transient currents, ensuring a clean power supply, and maintaining stable computing performance.

Solution 2: Conductive Polymer Tantalum Electrolytic Capacitors

Key Advantage: Available in ultra-thin and low-profile form factors, these capacitors meet the stringent space constraints and high-reliability requirements of server motherboards.

4) Storage for AI Servers

Addressing the diverse form factors and application scenarios of SSDs in AI servers, Yongming offers a wide range of capacitor solutions—covering everything from ultra-thin boot drives to high-density enterprise-grade SSDs—to meet Power Loss Protection (PLP) requirements. Our entire product line supports domestic substitution.

Solution 1: Polymer Hybrid Aluminum Electrolytic Capacitors (Solid-Liquid Hybrid)

Yongming’s NGY and NHT series of solid-liquid hybrid capacitors provide a highly reliable foundation for the domestic storage ecosystem. Key advantages include:

Safe Failure Mode: These capacitors fail in an "open-circuit" state. Unlike tantalum capacitors, which tend to fail via a short-circuit, this provides greater safety redundancy for high-value data storage systems, significantly reducing the risk of data loss caused by capacitor failure.

Ultra-Long Lifespan: The NGY series offers an exceptionally long service life of 10,000 hours at 105°C, while the NHT series supports extreme operating conditions of 125°C for 4,000 hours—meeting the requirements for enterprise-grade SSDs to operate at full load, 24/7, in high-temperature environments.

Exceptional Cost-Performance Ratio: While maintaining robust PLP performance, these capacitors reduce the Bill of Materials (BOM) cost to approximately 15% of that of tantalum capacitor-based solutions. They are the preferred choice for mainstream, high-capacity enterprise SSDs and cost-sensitive storage projects.

Solution 2: Liquid Aluminum Electrolytic Capacitors

For the power supply and filtering requirements of enterprise-grade solid-state drives (SSDs), Yongming provides liquid aluminum electrolytic capacitor solutions characterized by low Equivalent Series Resistance (ESR), compact dimensions, and a long service life.

PART 02

Hardcore Empowerment: Building the Foundation for AI Computing Power

Every watt of power and every bit of data in an AI server relies on the silent, essential support of capacitors. To address the high power consumption and heavy load challenges of the era of large-scale AI models, Yongming has developed a comprehensive portfolio of capacitor solutions covering power supply units, motherboards, and storage systems.
