Abstract : This thesis work deals with the design of an AC switch structure for specific ac mains applications 230V - 50 Hz. The targeted power level is about a hundred watts, and the currently used converter circuits make use of bidirectional switches that are realized using anti-series connected MOS transistors. Despite the improvements in performance provided by some of these structures, their fabrication cost is still high and limits their widespread diffusion in a market shared with the triac. We propose a current and voltage bidirectional bipolar device called a BipAC. It can be realized in an N-substrate (PNP BipAC) or a P-substrate (NPN BipAC). It can be controlled both to turn-on and turn-off with respect to a single reference electrode. It exhibits a very low on-state voltage that makes it attractive for specific mains applications with low load current (< 1A rms). The study of the BipAC structure is carried-out using 2D SentaurusTM physical simulations. In order to improve the current gain of the initial BipAC structure, a new version of the BipAC structure is proposed and its operating modes validated using 2D physical simulations (both process and electrical). Masks were then designed under CadenceTM software. The initial BipAC structure is realized on N and P substrates and for two different thicknesses. The operating modes of the monolithic bidirectional BipAC switch were validated through electrical characterizations.
