This paper deals with the static electrical modeling of the super-gain BJT which is dedicated to an innovative 600V AC switch solution which it gives birth to. As power bipolar component, its electrical modeling is based on the Gummel-Poon model which is widely accepted and used by researchers as well as circuit simulators such as Pspice. All of the model parameters are extracted from device characterization...
This paper mainly deals with the dynamic mode characterization of the super-gain BJT developed in the GREMAN laboratory and a low-loss 600V AC switch which it gives birth to. Firstly, the conception and validation of the super-gain BJT as well as the AC switch are presented followed by the static mode characterization of these innovative bipolar components in order to highlight their promising performance...
In this paper, a new monolithic bidirectional bipolar junction transistor with full turn-off control is studied due to technology computer-aided tools. The structure is built on a symmetrical transistor using silicon-on-insulator technology, which functionality relies on reduced surface field and base shielding effects. These concepts allow high drift doping concentrations and a thin and/or lowly...
In this paper, a physical model is proposed to estimate the TRIAC solder joints fatigue during power cycling. The lifetime prediction is based on the following assumptions: the case temperature swing (ΔTcase) is the main acceleration factor, the solder joints are the weakest materials in the TRIAC assembly, and the plastic strain within the solder layer due to shearing is the failure cause.
