Abstract

A hybrid series connection of a controllable switch (such as a BJT, an IGBT, or a GTO) and thyristors is proposed and studied. The proposed hybrid series connection has a controllable turn-off capability. The thyristors in the proposed connection are not turned off by auxiliary commutation circuits, but turned off by the series-connected controllable switch, so that burdensome auxiliary commutation circuits are saved. A hybrid series connection of a BJT (or an IGBT) and GTOs is also studied. The proposed hybrid series connection can be applicable to DC choppers, inverters, and ZVS (zero-voltage-switching) resonant converters in high voltage and high power applications.
