[0029] Hereinafter, the present invention will be further described in detail through specific examples in conjunction with the drawings. The present invention will be further described below in conjunction with the drawings.
[0030] Such as figure 1 , 2 As shown in, 3, 4, and 5, when the inductor current works in continuous conduction mode, according to the switching states of the two switching tubes, the topology has 4 circuit states. The working mode is divided into 0.5≤D below. <1 and 0
[0031] When the converter works at 0.5≤D In the interval <1, the circuit is divided into four stages:
[0032] (1)S 1 S 2 =11, such as figure 2 As shown in (D), the two-phase inductors are both in a charged state, the two diodes are reversely blocked, there is no conduction loop at both ends of the intermediate capacitor, and the voltage remains unchanged;
[0033] (2)S 1 S 2 = 01, such as figure 2 As shown in (C), the intermediate capacitor starts to be charged by the discharge ...
