The invention discloses a gate drive circuit without static power consumption, and belongs to the technical field of electronic circuits. A floating power supply ground module is used for generating afloating power supply ground signal and a high side reset signal, wherein a low voltage-high voltage level shifting module is used for shifting a low voltage driving signal of a front stage to a highvoltage side to control a high side power transistor; a high voltage-low voltage level shifting module is used for feeding back a high side signal of the floating power supply to a low side, and closing an input stage in the low voltage-high voltage level shift module through a logic control module to ensure that the gate drive circuit provided by the invention is free from static power consumption; and a drive output module drives the high side power transistor and a low side power transistor respectively by using the high side drive output unit and the low side drive output unit, and the logic control module provides logic control. The gate drive circuit is free from static power consumption, and meanwhile the problem of voltage resistance of a gate source is solved well.
