The Research of Switching Loss in Power Module Under the Small Sample Data
摘要
Abstract
The modeling of switching loss in power modules is important in practice for the prediction and evaluation of new energy system reliability. Using the power modules dynamic test system that can automatically adjust the DC bus voltage、collector current、gate drive voltage and gate resistance. Recording switching dynamic voltage and current waveforms to obtain precise switching loss values by processing. A switching loss model that improved the existing switching loss model based on a small sample of test points was established by SVM algorithm.关键词
