Abstract
- This paper deals with the design of an ac switch structure for specific ac mains applications 230 V–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. To replace the triac, an original current and voltage bidirectional bipolar device called a Bipolar ac (Bipac) is proposed, designed, realized, and characterized. 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 drop that makes it interesting for specific mains applications with low load current (0.5 $\text{A}_{{\text {rms}}}$). The study of the Bipac structure is carried out using 2-D Sentaurus physical simulations. The Bipac structure is realized on n-type and on p-type substrates for two different wafer thicknesses. The operating modes of the monolithic bidirectional Bipac switch were validated through electrical characterizations. [ABSTRACT FROM AUTHOR]
