The invention discloses a synchronous rectification leading edge blanking self-adaptive adjustment method adaptive to double-transistor flyback. The method comprises the following steps: detecting the turn-on time of a driving signal of a synchronous rectification controller and the high level time of a high-voltage detection signal; calculating a first duty ratio and a second duty ratio; judging whether a leading edge blanking time self-adaptive adjustment closed-loop condition is met or not; when the turn-on time of the driving signal is increased and is close to the high level time of the high-voltage detection signal, adjusting is stopped, and the current leading edge blanking time is maintained; and if the turn-on time of the driving signal is not increased to be greater than the leading-edge blanking time after the leading-edge blanking time is adjusted by the synchronous rectifier within the preset time range, the leading-edge blanking time is traced back to a default value. According to the method, the leading edge blanking algorithm is optimized in the synchronous rectification controller, so that the change of system power parameters is avoided to the greatest extent, the design complexity of a power supply system is reduced, and the risks of efficiency reduction and temperature rise and heating caused by repeated design and mistaken starting of the system are avoided.

This invention provides a threshold adaptive leading-edge blanking method for switching power supplies. It establishes an adaptive leading-edge blanking control loop, allowing the voltage threshold to adaptively change with load size or PVT influence through threshold adaptation. This invention enables adaptive leading-edge blanking and adaptive threshold selection. It continuously adjusts suitable stability conditions to adapt the voltage threshold, unlike traditional adaptive leading-edge blanking modules. The system automatically finds the optimal balance between anti-interference capability and detection sensitivity at any given time, significantly improving the robustness and reliability of the switching power supply under various complex operating conditions. Adaptive blanking shortens the physical dead zone, and the adaptive threshold immediately provides optimal detection sensitivity after the dead zone ends, thus achieving near-dead-zone-free high-reliability overcurrent protection. This invention also eliminates race conditions, reducing glitches in digital modules and improving the circuit's anti-interference capability.

The application discloses a Chinese-style porch modular roof structure, which comprises a plurality of rafters, a plurality of H-shaped keels, and a plurality of U-shaped main bodies of the H-shaped keels corresponding to the plurality of rafters. The bottom tile, cover tile module and integral looking tile board of the roof structure are all simulated through grooves to simulate the splicing joints of tiles and looking tiles, and the traditional tiles and looking tiles are restored in color, gloss and roughness to ensure the decoration effect. Meanwhile, the bottom tile and cover tile module adopt an integral structure to reduce joints and make the tile layer have better anti-seepage effect. The long back surface of the integral looking tile board is closely attached to the bottom of the wing edge of the H-shaped keel through a rubber strip, the splicing groove of the short back surface realizes a waterproof sealing structure through filling of sealing glue, and the integral looking tile board itself has no joint, thereby forming a second waterproof structure under the tile layer, further improving the waterproofness of the roof structure and reducing the risk of leakage.
