| description | The invention provides a method for determining the dead time of an active clamping flyback circuit, which relates to the technical field of electronic circuits. The method comprises the steps of generating a first voltage through the induction of an acquisition circuit and a primary circuit after a first switching tube is turned off, detecting the size of the first voltage, and determining a second dead time, wherein the first voltage has a corresponding relation with the voltage between the source end and the drain end of the first switching tube, and after the second switching tube is switched off, determining first dead time by using the input voltage, the output voltage, the turn ratio of the primary winding to the secondary winding and the oscillation period. The optimal dead time can be determined, and the purpose of reducing the system loss is achieved.
