Research on stray inductance extraction method for large-size power capacitor
Stray inductance present in the commutation loop of converters significantly impacts power semiconductor devices. However
accurately extracting stray inductance from large-size power capacitors remains challenging. While the discharge method is the current standard extraction technique
it is unsuitable for capacitors containing multiple resonance frequencies. Leveraging the high accuracy of the integral method in extracting stray inductance from busbars
an extension has been made to extract stray inductance from large-size power capacitors. Enhanced by a clarified error correction process
the results of the integral method are considered accurate. Despite the integral method yielding highly accurate results
it demands substantial testing resources
poses high-voltage safety hazards
and exhibits low efficiency. This paper presents a stray inductance extraction method utilizing an impedance analyzer
and provides a detailed explanation of the testing fixture and impedance compensation method. Comparing the results obtained from the impedance analyzer with those from the integration method revealed an error of less than 7.3%
which proved the accuracy of the proposed extraction method. In addition
this method offers convenient measurement
strong reusability and high efficiency
without the risks associated with high-voltage testing.
