Problems solved by technology

[0004] (1) The performance of components generally requires the components to reach the inherent design parameters under rated voltage and rated load conditions. Load conditions have a greater impact on the electrical performance and functions of components, which requires a large supporting simulation test load, and large Capacity simulation test load is not only costly, but also bulky

[0005] (2) The traditional large-capacity AC adjustable simulation test load adopts manual adjustment, which cannot realize automatic adjustment and precise control, and the loading accuracy is not high, and the matching calculation is large and time-consuming

In order to reduce the difficulty of work, a simplified mixed load is generally used, that is, there is an inductance or capacitance in the resistance component, which undoubtedly leads to the inability to realize the simulation of the real pure resistive, pure capacitive and pure inductive load, which affects the Accuracy and reliability of simulation tests
