Estimating the Power BJT Excess Charge Recombination Time Constant

Popis výsledku v původním jazyce

The paper demonstrates an experimental way of estimating the excess minority carrierscharge stored within the the power bipolar transistor in the saturation mode, i.e. with both junctionsforward-biased, as a reference to future IGBT switching action analysis. The method is based onanalyzing the transient turn-off base current waveforms at different conditions right before this event.The base current is known to supply the minority carriers within the device. Estimating the recom-bination time constant serves as a basal precondition for further identification of the excess chargestorage depending on various operating conditions and retrospectively an accurate identification ofpower BJT and IGBT various partial stage of switching action.
