AI Computing Power Surges: The Overlooked Foundation — Why Data Centers Need Stable Power More Than Chips
There is a noteworthy industry update: high-end PCBs are seeing a massive order boom. Some leading manufacturers have order backlogs stretching to 2027, and prices of high-speed PCBs have surged more than fourfold.
This news sends a clear signal: the AI computing boom has moved beyond concepts and down to the underlying hardware. From the "AI algorithm boom", to the "GPU boom", and now the "PCB boom", a chain reaction centered on computing infrastructure is in full swing.
So the question arises: what does this trend have to do with capacitors, reactors, APF and SVG that you focus on? The connection is substantial. It can even be said that the core competitiveness of AI data centers is shifting from "computing power competition" to "power infrastructure competition".
A single AI rack consumes as much power as a small factor.
Traditional data centers only required 5 to 10 kW per rack. In contrast, AI training clusters now see power density exceeding 40 kW per rack — 3 to 5 times that of conventional racks.
To make matters more challenging, the load of AI training tasks is highly dynamic. When GPUs switch between computation and communication phases, power consumption fluctuates sharply, causing instantaneous voltage variations. When a thousand-GPU cluster runs a large model training job that typically lasts days or weeks, a single voltage sag triggering node reboot can result in computing power waste equivalent to tens of thousands of US dollars in losses.
A real-world case: Green power + computing power, an ultimate test for power quality
In 2026, China’s largest single intelligent computing center was completed in Yiwu, Xinjiang. This computing power industrial park is equipped with Static Var Generators (SVG) to specifically address power quality issues. Why is such configuration required? Because core equipment such as servers and GPUs in computing centers are extremely sensitive to voltage stability. If voltage fluctuations exceed permissible limits, equipment malfunctions will occur, severely impairing the continuity and accuracy of large model training. After the SVG commissioning at the Yiwu computing power industrial park, the system power factor has remained steadily above 0.95, fully resolving power quality concerns.
The same scenario is unfolding at the Ulanqab Zero-Carbon Intelligent Computing Base. Tens of thousands of high-performance servers have been deployed in this base, whose computing loads feature high density, strong impact and transient fluctuations. After SVG units were put into operation, the power factor is stabilized at 0.99 ~ 1.0, the total harmonic distortion (THD) ≤ 3%, the failure rate of precision computing equipment has been cut by 60%, and the service life of equipment extended by 3 to 5 years.
These cases illustrate one key principle: the higher the computing power, the stricter the requirements for power quality. Capacitors, reactors, APF and SVG are the core equipment to guarantee power quality.
AI data centers are confronted with three major power quality issues: harmonic pollution, voltage fluctuation and reactive power impact. The four major product lines of Ningbo Dingnuo Electric precisely cover all these requirements.
Low-voltage shunt power capacitor — the "main force" for reactive power compensation Capacitors address reactive power compensation and voltage stabilization. Dingnuo Electric adopts high-quality polypropylene film combined with trapezoidal metallization technology, endowing capacitors with excellent self-healing property and capacitance stability. The wave slitting technology greatly increases the gold-sprayed contact area, delivering strong inrush current resistance, low annual capacitance decay rate, low temperature rise and long service life.
Low-voltage series reactor — the "gatekeeper" for harmonic mitigation Power modules, UPS and variable-frequency cooling equipment of AI servers are all typical non-linear loads, which inject massive harmonics into the power grid. When dry-type iron-core series reactors are connected in series with capacitors, they can effectively absorb grid harmonics, improve the system voltage waveform, restrain switching inrush current and switching overvoltage, and protect the safe operation of capacitors and server power supplies.
APF Active Power Filter — the "precision sniper" for harmonic mitigation While reactors adopt passive harmonic control (passive filtering), APF serves as an active and precision weapon. The APF Active Power Filter detects harmonic currents in the power grid in real time and actively outputs reverse compensation currents to cancel out harmonics. It is immune to grid impedance, featuring high compensation accuracy and fast response. Capable of dynamically tracking harmonic variations, it is especially suitable for scenarios with rapidly fluctuating loads such as AI data centers.
SVG Static Var Generator — the "all-round guardian" for voltage stabilization SVG is a new-generation dynamic reactive power compensation device, delivering faster and more accurate performance than traditional capacitor compensation. It adjusts reactive power output in real time via power electronic components with millisecond-level response time, effectively solving voltage flicker caused by instantaneous power fluctuations of AI server clusters. For new energy grid connection scenarios, SVG can also respond rapidly to random fluctuations of wind power and photovoltaic power, ensuring stable operation of computing centers amid volatile green power supply.
Capacitor: Compensates reactive power, stabilizes voltage, delivers fundamental power guarantee.
Reactor: Blocks harmonics, protects capacitors, provides passive grid protection.
APF: Precisely eliminates harmonics with active power governance.
SVG: Millisecond-level dynamic compensation, delivers ultimate rapid response.
For small and medium-sized data centers or power distribution sites with limited space, Dingnuo Electric offers anti-harmonic intelligent integrated power capacitor compensation devices. Integrating capacitors, reactors, switching switches and control systems in a single unit, this equipment achieves both reactive power compensation and harmonic suppression.
Zero-crossing switching: No inrush current impact and no switching overvoltage, with a switching lifespan of over 1.3 million operations. Multiple protections: Full suite of protection functions including over-temperature, excessive harmonic, phase loss, overvoltage and undervoltage. Intelligent networking: Multiple units can form a network automatically. A new master unit will be re-selected automatically if the original master fails, ensuring uninterrupted system operation. Split-phase compensation: Supports independent single-phase compensation for unbalanced three-phase loads.
Computing-Power & Power Coordination | The Next Major Opportunity
In 2026, the National Development and Reform Commission (NDRC) stated clearly that China’s investment in new power grids during the 15th Five-Year Plan period is expected to exceed 5 trillion yuan. Four authorities including the National Energy Administration jointly issued the Action Plan for Promoting Two-Way Empowerment between Artificial Intelligence and Energy, which puts forward the development of computing-power & power coordination: computing resources follow power supply, and computing facilities are deployed in an orderly manner in regions rich in new energy.
What does this mean? A large number of AI data centers will be built near new energy bases. Due to the volatility of wind power and photovoltaic power, such data centers have an inherent rigid demand for power quality management equipment (capacitors, reactors, APF, SVG).
Ningbo Dingnuo Electric Co., Ltd. is a manufacturer specializing in reactive power compensation and power quality management, integrating R&D, production and sales. It is a key enterprise of the China Electrical Equipment Industrial Association. With decades of in-depth industry engagement, the company has accumulated rich experience in reactive power compensation, backed by a team of senior engineers and a complete quality control system.
The energy concerns in the AI era are shifting from "computing bottlenecks" to "power infrastructure bottlenecks". Ningbo Dingnuo Electric stands right at the forefront of this emerging trend.
