Innovative power‑supply technologies are leading the industry, driving a win‑win outcome of enhanced energy efficiency and environmental sustainability in the power sector.

Against the backdrop of the global energy transition and the accelerated implementation of the “dual carbon” goals, the power sector is undergoing a profound transformation—from traditional energy sources to clean energy. As a core component of the energy system, innovation in power‑supply technologies not only enhances energy‑use efficiency but also directly determines whether the industry can achieve a green, low‑carbon transformation. In recent years, companies such as Yingjie Electric and Chint Power have, through sustained R&D investment and technological breakthroughs, improved power‑conversion efficiency and reduced energy consumption while developing end‑to‑end green solutions that span generation, storage, and consumption, thereby providing an important model for the high‑quality development of the power sector.

Technological Breakthrough: From Single-Scenario Efficiency Gains to All‑Scenario Adaptability

At the heart of power‑supply technology lies the efficient conversion and precise control of energy, achieved through power electronics. Leveraging its deep expertise in power‑control power supplies, Yingjie Electric has developed a comprehensive technological portfolio that spans diverse applications, including photovoltaics, semiconductors, and energy storage. Its custom‑designed specialty power supplies, featuring modular architecture and intelligent algorithmic optimization, boost conversion efficiency to over 98% while reducing energy consumption by more than 15% compared with conventional equipment. For instance, in photovoltaic manufacturing, Yingjie’s monocrystalline DC power supply employs dynamic voltage‑regulation technology to cut energy use during silicon ingot pulling by 20%; the annual energy savings from a single unit translate into a reduction of 120 metric tons of CO₂ emissions.

Chint Power, meanwhile, focuses on the needs of new‑energy applications and has launched a 320 kW high‑power string inverter that can operate at full power even in ambient temperatures as high as 50°C, supporting up to 1.1 times overload. Its system-level energy conversion efficiency is 8% higher than the industry average. Its liquid‑cooled energy storage system, POWER BLOCK 2.0, incorporates intelligent thermal management technology, reducing the cost per watt‑hour by 30% and extending its cycle life to over 20 years—effectively addressing the issue of efficiency degradation during long‑term operation. These technological advances not only enhance energy utilization but, thanks to their all‑scenario adaptability, also provide critical support for the large‑scale integration of new energy into the grid.

Green Practices: Low-Carbon Transformation Across the Entire Value Chain, from Production to End-to-End Operations

The greening of power‑supply technology is reflected not only in enhanced product performance but also throughout the entire lifecycle of corporate operations. Yingjie Electric has deeply integrated ESG principles into its development strategy, establishing a green management system that spans R&D, manufacturing, and recycling. In the production phase, the company has boosted water‑use efficiency to 95% through a closed‑loop water‑recycling system, with water intake per RMB 10,000 of output declining by 20% year over year in 2023. On the energy‑management front, it has created a seamless closed loop among photovoltaic generation, energy storage, and electric‑vehicle charging, achieving a 65% share of green electricity on its premises and reducing annual carbon emissions by 12,000 tonnes. Its mobile welding‑fume purification units and canteen‑oil‑fume filtration systems ensure exhaust emissions well below national standards. In 2023, the company obtained ISO 14001 certification for its environmental management system, cementing its position as an industry benchmark for green manufacturing.

Chint Power is driving the low-carbon transformation of the industry chain through a global footprint. In the North American market, its dual‑85 thin‑film capacitor inverters have reduced product failure rates from the industry average of 5% to 0.3%, cutting annual electronic waste by more than 200 tons. In South Korea, an IP67‑rated energy storage system designed for the region’s high‑humidity conditions has lowered equipment failure rates by 40% and extended service life by over five years. By combining technology transfer with localized manufacturing, Chint Power is helping energy systems in more than 30 countries and regions worldwide upgrade toward greater efficiency and reliability.

Collaborative Innovation: Building an Open and Symbiotic Technological Ecosystem

In response to the heightened demands that the new‑generation power system places on power‑supply technologies, companies are overcoming technical bottlenecks through cross‑sector collaboration. Yingjie Electric has established joint laboratories with Tsinghua University, the University of Electronic Science and Technology of China, and other institutions, achieving breakthroughs in areas such as silicon‑carbide power devices and digital‑twin technology. Its AI‑based power‑supply health‑management system can predict equipment failures up to 30 days in advance, boosting operational‑maintenance efficiency by 50%. Meanwhile, Chint Power has teamed up with upstream and downstream partners across the industry chain to develop standards for photovoltaic‑storage systems. The company’s flagship “PV + storage + intelligent control” solution, featuring a modular design, reduces system deployment time by 60% and enables rapid replication in commercial‑industrial parks, remote regions, and other settings.

Driven by both policy and market forces, innovation in power‑generation technologies is entering a virtuous cycle. China’s 14th Five-Year Plan explicitly identifies the development of a new‑type power system as a key priority, and in 2023, the share of non‑fossil‑fuel capacity in the country’s total installed generation capacity surpassed 50%, creating vast opportunities for power‑generation technologies. At the same time, the maturation of carbon‑trading markets and supportive green‑finance initiatives are further encouraging companies to ramp up R&D investment. According to statistics, in 2023, R&D spending in the power‑generation sector grew by 42% year over year, with patent applications exceeding 12,000, and the pace of technological iteration has accelerated markedly.

Looking Ahead: Technology Empowering Sustainable Development in the Power Sector

As digital and energy technologies converge, power‑supply technologies are evolving toward intelligence and service‑orientation. Ruijie Networks’ WAPI‑based trusted wireless solution for smart substations leverages AI‑driven radio‑resource allocation algorithms to reduce data‑transmission latency for substation inspection robots to below 10 milliseconds, providing critical support for the intelligent operation and maintenance of power equipment. Meanwhile, Yingjie Electric’s Ruijie Knowledge Brain platform integrates functions such as equipment‑fault prediction and energy‑efficiency optimization, boosting factory energy‑management efficiency by 30%. These innovative applications demonstrate that power‑supply technology has advanced from standalone devices to comprehensive system solutions, becoming a core engine in the construction of next‑generation power systems.

Under the guidance of the “dual carbon” goals, breakthroughs in power‑supply technology are not only critical to corporate competitiveness but also embody a mission of our times: driving the energy revolution and safeguarding the ecological environment. From enhancing conversion efficiency to reducing life‑cycle carbon emissions, from serving the domestic market to setting global standards, Chinese power‑supply companies are using technology as their brush to write a new chapter in energy transition and green development. Looking ahead, as cutting‑edge technologies such as materials science and artificial intelligence continue to permeate the field, power‑supply innovation will undoubtedly inject stronger momentum into the high‑quality development of the electricity sector, helping the global energy system accelerate its shift toward clean, efficient, and sustainable pathways.
