Abstract:
A drive circuit for driving a semiconductor element is equipped with: a first switch connected to a positive side of a DC power supply; a second switch connected to the other terminal of the first switch and to a negative side of the DC power supply; a third switch connected to the positive side of the DC power supply; a fourth switch connected to the other terminal of the third switch; a fifth switch connected to the other terminal of the fourth switch and to the negative side of the DC power supply; and a capacitor connected to the other terminal of the first switch and to the other terminal of the fourth switch. A gate of the semiconductor element is connected to the other terminal of said third switch; and a source of the semiconductor element is connected to the negative side of the DC power supply.
