IGBT (Insulated Gate Bipolar Translator) module minute-level power cycle testing device and control method

The invention relates to the technical field of testing, in particular to an IGBT module minute-level power cycle testing device and a control method, and the device comprises an oil storage tank, a cooling fan, a power circulator, an oil pump and a frequency converter. The oil pump comprises a driving motor and a junction box for controlling the driving motor to work, and the frequency converter is electrically connected with the junction box to control the junction box to work; the power circulator is provided with a test area for testing the IGBT module; the oil storage tank, the cooling fan, the test area, the oil pump and the oil storage tank are sequentially communicated through a pipeline to form a circulating oil path; according to the invention, the rotating speed of the oil pump is adjusted through the frequency converter, the flow speed of the heat dissipation oil is adjusted, and the real-time heat dissipation efficiency of the tested module is adjusted, so that different shell temperature differe
