Beschreibung
Zusammenfassung:	The utility model discloses an LLC switching power supply. The LLC switching power supply comprises a PCB; the inductor assembly comprises a first magnetic core and a first winding, the first winding comprises a first end and a second end, the first winding is wound on the first magnetic core, and the first end of the first winding is connected with the PCB; the transformer comprises a second magnetic core, a second winding and a third winding, the second winding comprises a third end and a fourth end, the second winding and the third winding are both wound on the second magnetic core, the third end of the second winding is directly connected with the second end of the first winding, and the fourth end of the second winding is directly connected with the third end of the third winding. And the fourth end of the second winding is connected with the PCB, so that the number of holes in the PCB in the switching power supply is reduced, and the power density of the switching power supply is improved. 本实用新型公开了一种LLC
