The present invention discloses a method for improving the primary-secondary disconnection problem of a primary-side feedback converter. The double-clamped zero-voltage switching converter performs closed-loop control by sampling the clamping capacitor voltage according to the relationship between the primary-side clamping capacitor voltage and the secondary-side output voltage, thereby achieving the output isolation and voltage stabilization function. However, when switching between empty and full load, the clamping capacitor voltage cannot timely reflect the change in the output voltage, and there is a problem of primary-secondary disconnection. The present invention proposes two methods for improving the primary-secondary disconnection problem, including: by detecting the clamping capacitor voltage, when the converter switches between empty and full load, a dynamic load is added to the clamping capacitor to increase the discharge rate of the clamping capacitor; and the closed-loop point of the clamping capacitor voltage is increased when the converter is empty and full load, and the change in the discharge voltage of the clamping capacitor is reduced. The method proposed by the present invention is relatively simple, saves space, and can effectively avoid the problem of severe output voltage drop caused by the empty and full load switching of the converter, greatly improving the reliability of the subsequent electrical equipment.
