China has developed industrial manufacturing technology and rich wind energy resources, so more and more wind turbines are being built.

[0003] As a link connecting wind turbines and the power grid, a wind power converter can convert the electrical energy generated by wind turbines to meet the requirements of power transmission and output it to the power grid. A converter usually consists of functional devices such as a circuit breaker, a contactor, a rectifier module, an inverter module, and a filter membrane module. The power module among them is the core of the entire converter, which is related to whether the entire converter can operate normally. Therefore, how to test the power module conveniently and quickly has always attracted much attention.
