Classification: CPC B | IPC B

Claim 2:
3. The drive circuit according to claim 1, wherein
when the level shift circuit transitions from the second mode to the first mode,
the second gate driver performs
a third control that outputs the third gate signal controlling the third transistor to be conductive and the fourth gate signal controlling the fourth transistor to be non-conductive, and then outputs the third gate signal controlling the third transistor to be non-conductive and the fourth gate signal controlling the fourth transistor to be conductive, and
a fourth control that outputs the third gate signal controlling the third transistor to be conductive and the fourth gate signal controlling the fourth transistor to be non-conductive after the third control, and then outputs the third gate signal controlling the third transistor to be non-conductive and the fourth gate signal controlling the fourth transistor to be conductive.
