description An embodiment of the invention relates to a synchronous rectification control method, circuit and device, equipment and a storage medium. The method comprises the steps of:acquiring a first drain-source voltage of a first MOS tube in a first rectifier tube in a target synchronous rectification circuit and a second drain-source voltage of a second MOS tube in a second rectifier tube; determining a first state corresponding to the first rectifier tube corresponding to the first MOS tube according to the first drain-source voltage, and determining a second state corresponding to the second rectifier tube corresponding to the second MOS tube according to the second drain-source voltage; determining a control strategy of the first MOS tube and the second MOS tube according to the first state and the second state; and controlling the first MOS tube and the second MOS tube based on the control strategy so as to control the target synchronous rectification circuit. Therefore, synchronous rectification control can be
