Abstract

The invention relates to a system and a method for testing the performance of alternating current sensitive components of an inversion control interface card of an inverter. The test system comprises a pre-control device, a signal generation device, a collection control device and a collection adaptation device; the pre-control device receives different test samples and respectively analyzes the test samples to different control commands; the signal generation device receives a signal excitation command and sends a test signal to the collection control device; the collection control device receives a test control command and the test signal and sends the test signal to the collection adaptation device according to the test control command; and the collection adaptation device receives the test signal, conditions the test signal and outputs the test signal to the inversion control interface card of the inverter to test the performance of the alternating current sensitive components therein. The test system and method provided by the invention are used for solving the problem that the interior sensitive components cannot be directly measured and automatically carrying out steps that require a lot of manual operations to liberate the testing personnel.
