The invention belongs to the technical field of electronic circuits, and relates to a no-bootstrap grid drive circuit with an active clamp. The no-bootstrap grid drive circuit with the active clamp comprises a control logic shunting unit, a drive enhancement circuit, an active clamp circuit, a power drive stage and an auxiliary discharge branch. The beneficial effects of the no-bootstrap grid drive circuit with the active clamp are that an upper power tube is driven by the mode of current driving so that joining of a high voltage floating power supply rail can be effectively avoided, and connection and disconnection speed of the upper drive power tube can be effectively adjusted according to the actual demands by adjusting impedance matching.
