“…However, their disadvantages are also obvious. According to the report of GREMAN laboratory [1], three main disadvantages are observed in real applications. The half-controllable problem is found in the Triac, the energy dissipation problem in permanent regime influences the performance of the solution IGBT+diodes and for the latest one, MOSFET+diode [2], which makes the cost of the solution expensive.…”

This article gives a modeling method based on the Gummel-Poon model for the Super-Gain BJT developed in the GREMAN laboratory. First of all, the extraction principle, mathematical calculating method, and final extraction results of each model parameter will be presented. Secondly, the Gummel and Voltage-Current output curves for a single Super-Gain BJT, which are carried on in Pspice with the extracted parameters in the first part, will be drawn and be compared with experimentation results. At last, a new 600V AC switch that is composed of two single Super-Gain BJTs connected in antiseries is simulated. To explain and reduce the error between the simulated results and experimental ones in hi-level injection, a new model with a dynamic resistance based on that of Gummel-Poon is proposed and validated. Consequently, all of simulations have an error less than 10%, proving the good precision of the models as well as the characteristics of the new AC power switch.

This paper deals with an innovative low-loss AC switch, named as TBBS (transistor based bidirectional switch), based on the association of super-gain BJTs developed by the GREMAN laboratory. The main characterization results of the super-gain BJT are reminded to identify the key parameters that are essential to build the TBBS. A complete characterization database in static mode of this new AC switch is discussed. In particular, its forward and reverse-biased features have been measured to see the evolution of the DC current gain as a function of the current density. The TBBS makes sense when using the super-gain BJT (bipolar junction transistor) in reverse mode. It means that the reverse DC current gain has to be sufficient (at least higher than 1 compared with the conventional BJT one). This new AC switch is bidirectional in current and voltage, totally controllable (turn-on and turn-off) and the most attractive solution in terms of on-state power losses. Further, its manufacturing process is as easier as existing device such as triac.
