IGBT Module Static Parameter Tester

I: IGBT Module Static Parameter Tester Main Features

Huake Zhiyuan Electrical Parameter Tester can be used for testing IGBTs in various package forms, and can also measure 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, and is applied in industries such as rail transportation, 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 such as inverters, wind power, rail transportation, and welding machines. It allows for separate testing after removal from the circuit board, enabling online IGBT detection. The testing process is convenient and simple. Parameters can be set directly in the test host for testing, or automatic testing can be performed after programming the host via software control. The static parameter testing of IGBTs is completed through computer operation.

Huake Zhiyuan's IGBT Module Tester is an intelligent test system developed for various static parameters of IGBTs. It features a high degree of automation (automatically operates according to the program set by the operator), records test results via computer, and stores test results in text format. The testing method is flexible (capable of testing discrete devices as well as single-unit and multi-unit modules), safe and stable (real-time monitoring of the equipment's working status and interlocking with hardware), includes safety protection functions, and offers fast and convenient testing speed.
