IGBT Static Parameter Test System

I: Main Features of the Static Parameter Test System

Huake Zhiyuan's electrical parameter tester can be used for testing IGBTs in various package forms, as well as measuring the V-I characteristics of high-power diodes, IGBT modules, high-power IGBTs, high-power bipolar transistors, MOSFETs, and other devices. It tests various power devices up to 600A (expandable to 2000A) and 5000V, widely applied in industries such as rail transportation, electric vehicles, wind power generation, inverters, and welding machines for IGBT incoming material selection and failure analysis. The equipment can also be used for online maintenance in industries like inverters, wind power, rail transportation, and welding machines, enabling online IGBT testing without the need to remove components from the circuit board. Testing is convenient and straightforward, with parameters set directly in the test host or automated via software-controlled programming. Static parameter testing of IGBTs is completed through computer operation.
