AI Technical Summary
Existing IGBT testing equipment lacks the ability to comprehensively test both static and dynamic characteristics, and the testing process requires frequent manual intervention, resulting in low efficiency and safety risks.
Design an IGBT testing system, including a signal conversion module, an IGBT testing circuit, a drive module, and a controller. The signal conversion module and drive module enable rapid switching between dynamic and static testing modes, integrated and unified control, and use relays and capacitors to simulate actual working conditions. A high-voltage power supply and a communication module are provided to ensure the safety and accuracy of the test.
It improves the efficiency and safety of IGBT testing, enables rapid switching between dynamic and static testing, reduces the need for manual intervention, and enhances the intelligence and reliability of the testing system.
