Abstract: Taking the choke transformer as the research background, this paper puts forward a new idea of the magnetization test circuit of the choke transformer based on the deep understanding of the field application of choke transformer and combined with the ability of existing test instruments and equipment. Through circuit design, the test scheme of choke transformer is as close as possible to the real state of use,  and the magnetization test of a single choke transformer is realized without using signal coil to aid the test, which makes the magnetization test of the choke transformer more real and effective. In order to verify its feasibility, a test environment is set up and the magnetization test circuit of the choke transformer is verified.
