An article on flexible aging testing

The power electronics industry is undergoing rapid iterative upgrading with expanding segmented markets. Products from new‑energy, industrial automation, medical electronics, AI computing and other sectors are updated at a fast pace, featuring a wide variety of categories and an enormous power range. Power‑electronic products for different industries have vastly different requirements for burn‑in test working conditions, load parameters and reliability standards. Conventional burn‑in equipment suffers from rigid configurations, poor adaptability and high reconfiguration costs. It cannot satisfy enterprises’ demands for co‑line testing of multi‑category and cross‑scenario products. Low equipment utilization and insufficient testing flexibility have become critical bottlenecks restricting product quality improvement and efficient production. Against such industry trends, modular and customizable intelligent burn‑in test solutions serve as a key enabler for quality improvement and efficiency gains across industries.

As a national‑level Specialized, Refined, Differential and Innovative “Little Giant" enterprise and the Guangdong Engineering Technology Research Center for New‑Energy Power‑Electronic Intelligent Detection Technology and Complete‑set Equipment, CPET Zekeyuan has long engaged in power‑electronic reliability testing. Centered on the urgent quality‑inspection needs of diverse industries, it breaks the industry‑adaptation barriers of traditional equipment via modular hardware architecture plus exclusive custom test solutions. Its systems flexibly support burn‑in verification for full‑range power‑electronic products across multiple sectors, balancing test accuracy and production‑line flexibility to help enterprises consolidate product quality foundations.

CPET’s burn‑in test equipment adopts an innovative building‑block‑style modular design. Core components including source‑load modules, temperature‑control units, data‑acquisition units and station modules can be freely combined and flexibly deployed. Enterprises can select functional modules such as loads, temperature controllers and interfaces according to the power rating of units under test, number of test channels, practical working‑condition requirements and factory‑floor layout, so as to rapidly build dedicated burn‑in test systems. Fine‑tuning of modules enables quick adaptation to products ranging from low‑power adapters and LED driver power supplies to high‑power energy‑storage converters, vehicle‑mounted electronic control systems and high‑end server power supplies. This greatly cuts repeated equipment procurement costs, maximizes hardware reusability and delivers cost and efficiency benefits for enterprises.

Benefiting from strong modular regulation capabilities, the equipment supports diverse composite burn‑in test modes including wide‑range precise temperature control, dynamic stepped loading, voltage fluctuation shock and long‑duration full‑load operation. It highly reproduces complex real‑world application scenarios of products, accurately triggers latent performance defects and intercepts quality risks before products leave the factory. Moreover, multiple stations can run independently in parallel. Distinct test parameters may be set for each station to realize simultaneous burn‑in of multiple product types. It seamlessly covers all testing phases including R&D sample validation, small‑batch trial production and large‑scale mass production.

At present, CPET Zekeyuan’s custom burn‑in solutions have been deployed in many mainstream industries to boost quality of full‑range power‑electronic products. In the new‑energy sector, it performs long‑term charge‑discharge cycle burn‑in for energy‑storage power supplies, photovoltaic inverters and on‑board on‑board chargers (OBC). For AI computing and industrial control, it simulates extreme high‑load conditions to verify operational stability of server power supplies and industrial drive power supplies. In consumer electronics and lighting, it meets demands for large‑volume standardized centralized burn‑in of adapters and LED drivers. It also satisfies stringent temperature‑variation testing and high‑reliability inspection standards for medical and military‑grade electronics, covering mainstream power‑electronic product categories.

Built upon flexible hardware adaptation, CPET Zekeyuan provides self‑developed intelligent test software to deliver digital and intelligent whole‑process test management. It supports custom parameter editing and one‑click fully‑automatic testing for stable 7*24‑hour unattended operation. The equipment collects multi‑channel real‑time data of voltage, current and temperature, triggers automatic alerts for abnormalities, preserves full test logs, and generates traceable standardized test reports. It enables seamless connection with factory management systems such as MES and ERP, meeting enterprises’ traceability requirements for factory audit verification and process iteration. In addition, high‑efficiency energy‑feedback technology recycles electric energy generated during burn‑in tests. Compared with traditional resistive‑load equipment, it substantially reduces workshop power consumption and electricity expenditure and facilitates enterprises’ shift toward green intelligent manufacturing.
