Dual Breakthroughs in Energy Saving and Precision

Driven by the in-depth advancement of the dual-carbon goals and the upgrading demand for high-end power supply quality, the power supply burn-in test equipment industry is facing dual challenges of "energy saving and cost reduction" and "precision testing". Traditional equipment generally has pain points such as high energy consumption, large test errors, and narrow applicable scenarios, which are difficult to meet the stringent requirements for test efficiency and quality in fields such as new energy and aerospace. The new generation of power supply burn-in test equipment has achieved two-way empowerment of "energy saving" and "precision" through revolutionary breakthroughs in energy-saving technology and comprehensive upgrading of precision testing systems, establishing a new technical benchmark for the industry and injecting core momentum into the high-quality development of the electronic industry.

The revolutionary innovation in energy-saving technology has subverted the high-energy-consumption model of traditional burn-in testing. Traditional power supply burn-in test equipment adopts an "energy-consuming" design, where a large amount of electrical energy generated during testing is lost in the form of heat, with a comprehensive energy efficiency of less than 60%. Especially in high-power and long-term testing scenarios, huge energy consumption has become a heavy burden for enterprises. The new generation of equipment, focusing on "energy feedback + intelligent regulation", has achieved a leap in energy-saving efficiency: equipped with a high-efficiency energy feedback module, it can accurately feed back the electrical energy output by the power supply during testing to the power grid, with a feedback efficiency of more than 92% and a comprehensive energy efficiency exceeding 90%, reducing energy consumption by 40%-60% compared with traditional equipment; integrated with AI intelligent load adjustment algorithm, it can dynamically adjust the load size according to the power supply testing needs, avoiding invalid energy consumption under light load conditions, and at the same time, combined with the intelligent sleep mode, it automatically reduces the equipment operating power when there is no testing task, further reducing standby energy consumption. Taking Cosail Electronics' energy-saving burn-in equipment as an example, its three-phase balanced energy feedback technology can effectively avoid grid harmonic pollution, which not only meets the cost reduction needs of enterprises, but also conforms to the low-carbon development requirements under the dual-carbon goals, becoming the core choice for new energy enterprises.

The comprehensive upgrading of the precision testing system has built a solid quality barrier for high-end power supplies. With the popularization of high-end products such as wide-bandgap semiconductor power supplies and automotive power supplies, higher requirements have been put forward for the precision and dynamic response capability of burn-in testing. The test error of more than ±1% and second-level response speed of traditional equipment can no longer meet the needs. The new generation of equipment has built a precision testing system from three aspects: sensors, algorithms, and architecture: adopting high-precision Hall sensors and temperature sensors, the voltage and current testing accuracy is improved to ±0.1%FS, and the temperature control accuracy reaches ±0.5℃, which can accurately capture the subtle performance attenuation of the power supply; implanted with an adaptive calibration algorithm, it real-time corrects the environmental interference errors during the testing process, and eliminates data noise combined with digital filtering technology to ensure the stability and authenticity of test data; optimized the test architecture to achieve millisecond-level dynamic load response, which can accurately simulate the operation status of the power supply under complex working conditions such as load mutations and voltage fluctuations, and completely reproduce the actual use scenarios of high-end power supplies. For the testing needs of aerospace-grade power supplies, some high-end equipment has also added extreme environment simulation modules, which can complete precise testing under harsh conditions such as wide temperature range of -40℃ to 85℃ and high-voltage insulation, and the test data can directly support product reliability certification.

The dual breakthroughs in energy saving and precision have not only solved the core pain points of the industry, but also established a new technical benchmark, promoting the transformation of burn-in test equipment from "basic verification tools" to "high-end quality empowerment carriers". For enterprises, energy-saving technology can greatly reduce testing costs, and precision testing can eliminate defective products in advance and shorten the R&D cycle. The dual advantages help enterprises improve their core competitiveness; for the industry, this technological breakthrough has accelerated the localization substitution process of high-end test equipment, broken the monopoly of foreign brands in the field of high-precision and energy-saving equipment, and promoted the upgrading of industry technical standards. At present, burn-in equipment with dual breakthrough capabilities has been widely used in high-end scenarios such as new energy vehicles, AI computing centers, and aerospace, and has been recognized by well-known enterprises such as CASIC and leading automobile manufacturers.

In the future, with the in-depth integration of technologies such as AI and digital twins, power supply burn-in test equipment will achieve further breakthroughs in energy-saving efficiency and test precision, and at the same time iterate towards intelligence and integration. The dual core advantages of energy saving and precision will continue to lead the development direction of the industry, provide more solid technical support for the quality upgrading of the high-end electronic industry, and write a new chapter in industry technological innovation.
