The invention discloses a method for producing a non-overlapping signal with reasonable dead-zone time. In the method, the non-overlapping signal with reasonable dead-zone time is produced by adopting double loops (an inner loop and an outer loop) so as to obtain the appropriate dead-zone time. In the inner loop, the steps are implemented by NAND gate or NOR gate through logic operation, and the phenomenon that last driving tubes are in a state of synchronous conduction is avoided; meanwhile, in the outer loop, an inner loop signal is further controlled by taking the appropriate delay of the non-overlapping signal produced in the inner loop as a feedback signal so as to obtain the non-overlapping signal with appropriate dead-zone time. In the method, digital signals are used for controlling the dead-zone time of the non-overlapping signals in two closed-loop systems; and circuits are simple and easy to debug and reliability is high.
