开关电源
摘要：
一种开关电源包括：多个并联支路，每个并联支路包括两个串联连接的可控开关(111、112)和连接在两个开关(111、112)与输出节点(150)之间的线圈(141)；电容器(152)，连接在并联支路的输出节点与接地(154)之间；以及控制器(160)，该控制器(160)被配置为切换每个并联支路(401、402、403)的两个串联连接的可控开关(111、112)使得当流过并联支路的线圈(141)的电流(I1)达到大于5A的第一电流值时，将并联支路的第一开关(111)从导通状态切换至非导通状态，并且使得当流过并联支路的线圈的电流达到小于0A的第二电流值时，将第二开关(S2)从导通状态切换至非导通状态。
摘要（英）：

A switching power supply includes a plurality of parallel branches, each parallel branch comprising two serially connected controllable switches (111, 112) and a coil (141) connected between the two switches (11, 112) and an output node (150), a capacitor (152) connected between the output node of the parallel branches and ground (154); and a controller (160) configured to switch the two serially connected controllable switches (111, 112) of each parallel branch (401, 402, 403) such that a first switch (111) of a parallel branch is switched from a conducting state to a non-conducting state when a current (I1) flowing through a coil (141) of the parallel branch reaches a first current value larger than 5 A, and such that the second switch (S2) is switched from a conducting state to a non-conducting state when the current flowing through the coil of the parallel branch reaches a second current value smaller than 0 A.
