The invention discloses a synchronous rectification drive circuit applicable for simultaneously feeding back and outputting the drive energy of two synchronous rectifying tubes of T-type voltage-double rectification, which comprises a clamping and energy feedback circuit, a high frequency transformer T1, a current transformer CT1, a middle energy storage capacitance C1, an output capacitor C2, a synchronous rectifying tube SR1, a synchronous rectifying tube SR2 and two drive circuits respectively used for driving the synchronous rectifying tube SR1 and the synchronous rectifying tube SR2. Thecurrent controlled synchronous rectification drive circuit is characterized in that the drive of an upper tube in a bridge arm for outputting the voltage-double rectification can be clamped on the middle energy storage capacitor C1 and the redundant drive energy of a lower tube can be recycled to the same energy storage capacitor C1. The current controlled synchronous rectification drive circuit has the beneficial effects that: 1, the drive energy can be fully recycled and the efficiency can be improved; 2, the design requirement of the transformer can be reduced; the number of turns of the signal windings can be reduced and the cost can be reduced; 3. the current controlled synchronous rectification drive circuit can be used for the drive circuits of two transformers and can also be usedfor the drive circuit of single current transformer; and the application occasions are flexible.
