Recently, the "T/HBAS 066—2024 Technical Requirements for High Current Pulse Power Supply" group standard, led by Wuhan PRECISE Instrument Co., Ltd. (hereinafter referred to as "Pusais Instrument"), and jointly drafted by multiple units, was officially released. This standard is under the management of the Hubei Provincial Association for Standardization and will come into effect on September 30, 2024. The content covers multiple aspects such as production, use, and inspection of high current pulse power supplies, and specifies in detail the appearance and interface requirements, performance requirements, functional requirements, safety requirements, as well as inspection rules, packaging, transportation, and storage of the power supply. The aim is to promote the scientificity and practicability of high current pulse power supply products and provide standardized technical guidance for the industry.
In recent years, Hubei Province has attached great importance to the work of standardization construction and actively promoted the formulation of standards for emerging business forms, helping market entities seize the development window. The release of this standard is also one of the important achievements of the provincial-level group standardization work in Hubei Province. It will further promote the standardization and normalization development of high current pulse power supply technology in Hubei Province and even throughout the country.
PRECISE Instruments has long been dedicated to the research and development of equipment for testing the electrical performance of semiconductor materials and devices. Its products cover the entire industrial chain from materials, wafers to devices. The recently published "Technical Requirements for High Current Pulse Power Supply" group standard is based on the company's rich market experience in semiconductor testing instruments and its profound technical accumulation in high current pulse power supply technology.
During the testing process of semiconductor materials and devices, the high current pulse power supply, as one of the key equipment, its stability and reliability directly affect the accuracy of the test results. The high current pulse power supply independently developed by PRECISE Instrument has the features of large output current (1000A), steep pulse edges (typical time 15μs), support for two-channel pulse voltage measurement (peak sampling), and support for output polarity switching. It can meet the requirements of high-precision testing for Schottky diodes, rectifier bridge stacks, IGBT devices, etc., and can effectively improve the test efficiency and product quality. Currently, the high current pulse power supply of Pusai Instrument has been applied in the laboratories/production lines of many well-known semiconductor enterprises and has been widely recognized.
01 High current output with fast response and no overshoot.
The high current pulse power supply independently developed by Pusheis Instrumentation features a fast response during the pulse output establishment process without overshoot. During the testing process, the typical rise time of the large current is 15 μs, and the pulse width can be adjusted within the range of 50 to 500 μs. This enables effective reduction of errors caused by the device's own heat generation.
(Test conditions: Load resistance 5 mΩ / 1000A current probe test)
02 Precise measurement and versatility
Supports two-channel pulse voltage measurement (peak sampling), and has high-precision (0.1% FS ± 1A) current output capability. Meanwhile, it also supports polarity switching of output and parallel output of multiple devices, with a maximum parallel output capacity of up to 6000A, meeting the requirements of large current testing.
03 Extensive application fields
It is widely applied in the tests of Schottky diodes, rectifier bridge rectifiers, IGBT devices, IGBT half-bridge modules, IPM modules and other semiconductor devices. It can independently complete the "current - conduction voltage" scanning test, providing strong support for the performance verification of the devices.
04 Advanced technology and stable performance
By adopting advanced control technologies and optimizing circuit design, the product's stable performance and long service life are ensured. Meanwhile, this power supply also has a complete protection mechanism to ensure that the output can be quickly cut off in abnormal situations, thereby protecting the safety of the test equipment and the tested components.
In the future, Wuhan Pusais Instrument Co., Ltd. will continue to uphold the concepts of innovation and pragmatism, and will continuously promote the research and application of semiconductor testing equipment technology. At the same time, the company will also actively participate in more standardization work, promoting the continuous improvement and enhancement of industry standards, and contributing wisdom and strength to the high-quality development of the semiconductor industry.
