This invention relates to the field of insulation performance testing technology, specifically to a multi-band series resonant high-voltage testing device and its impedance matching method. The method involves multi-band frequency sweeping of the device under test (DUT) to acquire and finely sweep the target frequency band. Based on the frequency, peak width, and amplitude of the peak points during the fine sweep, a reference degree is obtained to screen out the true resonant points within the target frequency band. The load on the DUT is adjusted, and based on the changes in the reference degree, quality factor, and amplitude of the true resonant points under different loads, a predominance degree is obtained to distinguish between the main resonant point and local resonant points. Impedance matching is performed based on the frequency of the main resonant point to conduct a voltage boost test. The insulation performance of the DUT is evaluated for each voltage boost test based on the predominance degree of the main resonant point and the number of local resonant points after voltage boost. This invention effectively improves the accuracy of impedance matching and insulation assessment by accurately screening out the main resonant point, avoiding test deviations caused by interference, and ensuring the reliability and safety of high-voltage testing.
