Abstract:
A normally-on bidirectional switch, including, in parallel between two power terminals of the switch:a cathode-gate thyristor having a gate and an anode, the anode of the cathode-gate thyristor being connected to a first power terminal of the two power terminals;an anode-gate thyristor having a gate and an anode, the anode of the anode-gate thyristor being connected to a second power terminal of the two power terminals; anda series association of a resistor electrically coupled in series with a controllable switch, a midpoint of the series association being connected to the gate of the cathode-gate thyristor and to the gate of the anode-gate thyristor, the gate of the cathode-gate thyristor being distinct from the gate of the anode gate thyristor.
