Abstract:
A semiconductor device 101 in a bi-directional switch includes: a first electrode 109A, a second electrode 109B, a first gate electrode 112A, and a second gate electrode 112B. In a transition period: when the potential of the first electrode 109A is higher than the potential of the second electrode 109B, a voltage lower than the first threshold voltage is applied to the first gate electrode 112A and a voltage higher than the second threshold value voltage is applied to the second gate electrode 112B; and otherwise, a voltage higher than the first threshold value voltage is applied to the first gate electrode, and a voltage lower than the second threshold value voltage is applied to the second gate electrode.
