With the continuous development of power electronics industry, the application of IGBT module is more and more extensive. In the modern industrial field, IGBT modules have become indispensable components in various high-power electronic devices, such as motor drivers, motor controllers, inverters, and solar inverters. As a key component, improving the performance and reliability of IGBT modules is essential for the development of the entire electronics industry. The UL1557 certification is one of the standards to ensure the electrical safety of IGBT modules. Applying for UL1557 certification is a guarantee of the quality of IGBT modules and a necessary means to enter the international market.
IGBT module in UL 1557 certification main test items:
structural integrity testing:
l Check whether the mechanical structure of the module is complete and free from damage or defects.
l Evaluate the strength and durability of the module housing and internal structure.
Electrical performance testing:
l Measure the electrical parameters of the IGBT module, such as on-resistance, saturation voltage drop, threshold voltage, etc.
l Verify the electrical performance of the module under different temperature and load conditions.
Thermal performance test:
l Evaluate the thermal stability of the module under different ambient temperature and load conditions.
l Test the thermal performance and thermal resistance of the module.
Insulation performance test:
l Measure the insulation resistance and insulation strength of the module.
l Check that the electrical isolation between the inside and outside of the module is satisfactory.
Reliability testing:
l Conduct reliability tests under long-term operating conditions to evaluate the life and stability of the module.
May include temperature cycling test, humidity test, vibration test, etc.
Safety protection test:
l Evaluate the protection functions of the module, such as overcurrent protection, overheating protection, etc.
l Check the response and self-protection ability of the module in abnormal situations.
Electromagnetic compatibility (EMC) testing:
evaluate the anti-interference ability of the module in the electromagnetic environment and the influence of electromagnetic radiation on other equipment.
Environmental adaptability test:
test the performance of the module under different environmental conditions, such as high temperature, low temperature, humidity, salt spray, etc.
Tag and File Review:
l Review the marking, labeling and instructions of the module for compliance with UL standards and relevant regulatory requirements.
l Verify that the technical documents and data provided by the manufacturer are accurate and reliable.
