Abstract :
This paper designs a drive circuit of MOSFET for ultrasonic power. The requirements of high-speed drive circuit of MOSFET are presented based on the turn-on and turn-off processes. The design and implementation process of MOSFET driver circuit which meets the requirements of operation frequency to 1 MHz, electrical-isolated, strong driving capability, are discussed in detail. And the feasibility of the drive circuit is proved.
