Control device for double gate semiconductor device. |
摘要 |
<p>A control device (20) includes a first gate control circuit (21) for supplying a control signal from a control signal inputted to an input terminal P1 to a gate G1, and a second gate control circuit (22) for supplying a control signal from a control signal inputted to the same input terminal P1 to a gate G2. The first gate control circuit (21) is provided with a delay circuit (31), and after a turn-off signal is supplied to the gate G2 for the transition from a thyristor condition to a transistor condition, a turn-off signal is supplied to the gate G1, thereby positively stopping operation of the double gate semiconductor device. <IMAGE></p> |
