摘要： PROBLEM TO BE SOLVED: To provide a low-loss gate drive technique by preventing overcurrent and overvoltage incidences in various components in unintended transient periods, when a bidirectional device is applied as a semiconductor device applied to an inverter or the like. SOLUTION: There is provided the gate drive technique that controls a bidirectional switch 1 which is equipped with a first gate terminal 2, a second gate terminal 3, a drain terminal 4, and a source terminal 5, and possesses four operating modes in which the first gate terminal 2 and second gate terminal 3 are variously ON and/or OFF.

The gate drive technique operates the bidirectional switch 1 mainly in an operation mode without bidirectional intervention of a diode, and can operate the bidirectional switch 1 with intervention of the diode in the transient periods, thereby obtaining effects of preventing overcurrent and overvoltage incidences in the various components.
