At present, global intelligent manufacturing is accelerating its progress, and new energy, digital infrastructure, and high-end equipment industries are booming. Power electronics, as the core carrier for power conversion, energy regulation, and the operation of intelligent equipment, is widely applied in key fields such as new energy vehicles, photovoltaic energy storage, LED lighting, industrial power supplies, network communications, medical electronics, and industrial control drives. With the upgrading of market demand, downstream terminals have higher requirements for the environmental adaptability, operational stability, long-term durability, and safety reliability of electronic products. Product quality has become the core lifeline for enterprises in market competition, brand accumulation, and sustainable development.
Shenzhen Zhongke Yuan Electronics Co., Ltd. (CPET) is deeply rooted in the core area of Shenzhen's electronic manufacturing industry. Since its establishment in 2010, CPET has always focused on the field of power electronic reliability testing. Its main business includes the research, production, and customization of digital aging testing equipment, ATE automatic testing systems, and intelligent equipment for fully automatic or semi-automatic integrated production lines. As a national-level "Specialized, Innovative, Precise, and New" (small-sized) "Giant Enterprise", CPET addresses the production pain points of the industry, with its core being independent measurement and control technology and guided by digitalization and intelligent manufacturing. It builds a standardized quality control system for all working conditions, full-process control, and full-cycle verification for power electronic products in various industries. From research and development verification to mass production aging, it comprehensively strengthens the product quality defense line, and with practical manufacturing capabilities, it empowers the high-quality upgrade of the electronic manufacturing industry.
In the research, development, debugging and mass production of power electronic products, most quality problems do not manifest immediately but are latent in continuous load operation, voltage fluctuations in the power grid, complex outdoor climates, high-frequency start-stop operations, etc. The traditional testing mode relies on simple high-temperature baking, single configuration load and manual inspection. The testing form is monotonous, the simulation of working conditions is one-sided, and it cannot restore the real usage environment of the product. At the same time, there are problems such as high labor input, cumbersome operation, scattered data, inability to trace back, and energy waste. Hidden defects such as parameter drift of components and insufficient heat dissipation design are difficult to be detected in advance, which may lead to early failure of the terminal products, a sharp increase in after-sales repair rates, increase in enterprise costs, affect brand reputation, and restrict large-scale development.
In response to the industry quality control challenges and production demands, CPET closely follows the actual situation on the front line, continuously iterates its core technologies, and builds an integrated, modular, and digitalized aging test equipment matrix. It breaks through the limitations of traditional equipment and realizes intelligent simulation of working conditions, automatic on-site control, digital data management, and customized scenarios. It precisely matches the differentiated needs from small and medium-sized factories to large intelligent workshops, and has become the preferred solution for reliability verification and quality control of products in the power electronics industry.
The CPET series intelligent aging testing equipment is equipped with an independently developed core control system. Its hardware architecture is stable and runs smoothly. It strictly complies with international industry standards such as IEC 60749-34-1:2025, ensuring accurate and compliant testing. The equipment can achieve various complex testing modes such as wide-range temperature regulation, dynamic step load, high and low pressure fluctuation impact, and long-term full-load continuous aging as per customer requirements, closely matching the actual application environment of the products. Through the principle of accelerated aging, it quickly triggers potential hazards, efficiently screens out defective products, verifies the rationality of product design and the durability of the entire machine, strictly controls the yield rate from the source, and reduces the risks of after-sales and maintenance.
In terms of intelligent control and practicality, the equipment is equipped with a high-definition human-computer interaction interface, which is simple to operate. It supports one-click startup, parameter customization, multi-station synchronous independent operation and 24-hour unmanned operation, significantly reducing the need for human intervention. It is suitable for the production rhythm of factories. The entire machine is equipped with a high-precision acquisition unit, which can real-time monitor key data such as voltage, current, and temperature of each product. It automatically stores, uploads, backs up to the cloud, and generates test reports and logs. The data can be queried, traced, and exported. It meets the needs of customers for factory audits and process optimization, and seamlessly integrates with enterprise MES, ERP and other digital management systems, helping to achieve digital transformation of the workshop.
In line with the factory's cost reduction and efficiency improvement as well as the demand for green production, CPET has independently developed an energy feedback energy-saving technology. This technology can recover the surplus electrical energy generated during aging tests, reducing equipment energy consumption and the electricity cost in the workshop, and aligning with the trend of green and low-carbon development. The equipment is designed in a modular manner, with flexible structure and strong scalability. It can be customized according to product size, power, test quantity, and site conditions, and is widely compatible with various types of power electronic products such as switching power supplies, vehicle electronic control components, photovoltaic inverters, and communication power supplies. It has strong versatility and is suitable for a wide range of scenarios.
Relying on mature technologies and service experience, the CPET aging testing equipment has been deeply implemented in various mainstream industries. In the field of new energy vehicle charging, it simulates the strict driving conditions to verify the stability of components such as vehicle chargers and BMS; in the field of photovoltaic energy storage, it simulates the complex outdoor environment to test the load-bearing capacity and lifespan of inverters and charging piles and other equipment; in the LED lighting industry, it supports large-scale centralized aging to screen common problems in mass production and improve the yield rate of shipments; in the high-standard fields such as industrial control, communication, and medical care, it conforms to industry norms and meets the strict operation requirements of equipment, laying a solid safety foundation.
Apart from the core aging testing equipment, CPET has established a three-in-one layout of "intelligent aging testing equipment + ATE automatic comprehensive testing equipment + fully automatic/half-automatic customized production line". Relying on the experience of line integration, it can provide a one-stop customized solution from single-item testing, complete machine inspection to line-body linkage, covering the entire process, simplifying procedures, increasing production capacity, and helping enterprises achieve the upgrade of the entire process of intelligent manufacturing. Among them, the ATE automatic testing system adopts an open architecture, can customize test commands, is compatible with multiple programming languages, realizes parallel testing of multiple devices, and improves efficiency and accuracy.
