The rapid progress of electronics technology has led to significant advancements in research, production, quality, and industrial testing. Programmable DC power supplies, AC power supplies, and electronic loads, as widely applicable test equipment, have been categorized as power electronic measuring instruments. As fundamental test and measurement tools in the field of power electronics, they play a crucial foundational role. They are extensively used in traditional and emerging industries such as aerospace, power electronics, new energy, industrial automation testing, electrochemical energy storage, battery testing, and passive and active component testing.
Established foreign brands with an early entry into the programmable source loader testing field have accumulated some advantageous overseas manufacturers, such as Germany's EA, the U.S.'s Keysight, and Taiwan's Chroma. In recent years, with the rise of domestic brands, the highly competitive Chinese market has seen a differentiated shift in market demand, influenced by national policies and guidance. Specific requirements for source loader testing equipment have emerged across various sectors. Especially in China, the aerospace, automotive, new energy, energy storage industries, and universities have all triggered this substantial market demand potential.
With the rapid advancement of the new energy and energy storage industries, there is an increasing demand for diverse power testing and load requirements, including bidirectional DC power supplies, high-power DC power test systems, and energy recovery electronic load systems. As the technology gap between domestic and international markets narrows, with domestic technology achieving parity and even surpassing foreign technology, the market has seen the emergence of a batch of power brand manufacturers with technical advantages and customization capabilities, such as IDEC, Loyi Technology, and AKEBO, etc. Compared to some mainstream foreign manufacturers, they have a strong competitive edge in terms of cost-performance and product quality. In addition to high-power density and series-parallel module solutions in hardware, they also offer standard test curves and customized solutions in software. Especially Loyi Technology's high-power density, large current DC power supply, with a single module current up to 1000A and as high as 20000A, is mainly applied in the fields of photovoltaic/storage: grid-connected inverters/storage converters; new energy vehicles: on-board chargers/DC-DC modules, vehicle-mounted components; medium and high-power motors: electric vehicle motors, aircraft/ships/aerospace motors; batteries: cells, battery modules, capacitors, etc. It is also known as a dedicated test power supply in the automotive sensor testing field, forming differentiated competition against traditional programmable DC power supplies.
Source equipment (programmable AC/DC power supplies and electronic loads) serves as fundamental equipment for laboratory and industrial testing. Amid the increasingly intense international trade war, domestically produced equipment is the foundation of the nation, and it has gained national attention in recent years. The influence of the policy environment and the growing support for domestic outstanding manufacturers are becoming increasingly evident. Particularly, brand manufacturers with a strong technical foundation domestically are receiving significant attention.
