摘要：
A new mode of triggering in a bi-directional MOS-thyristor device is described and its operating modes are verified using 2D numerical simulations. This device is a vertical MOS controlled bi-directional structure that can be used as an AC switch for mains applications. It uses a P+ wall that extends from the top surface to the bottom of the wafer and ensures, in addition to blocking anode voltages, the turn-on of the device in the third quadrant of operation by using a lateral IGBT. This device has the advantage of being controlled by MOS and it requires a technological process fully compatible with that of the IGBT for its realization. Moreover, a description of most of the proposed devices to be used as AC switches is given in this paper in order to highlight the major difficulties encountered in designing MOS-gated bi-directional switches.
