Background technique
LLC topology can realize Sofe Switch in wider loading range, help to realize efficient, high power density
Target, thus be used widely in power inverter field；In order to further increase power density and efficiency, multiphase is used
LLC topology is one of selection in series and parallel.For each phase LLC, all contain two magnetic of resonant inductance and main transformer
Property element, to multiphase LLC, volume is larger if using discrete device, higher cost；There is magnetic Integrated Solution at present,
Multiple magnetic devices are integrated on a magnetic core, can solve the above problem to a certain extent；It is existing for three-phase LLC topology
Have there are two types of technical solutions, one is discrete device is used, volume is larger while being unfavorable for improving efficiency；Magnetic is used there are also a kind of
Integrated device, the program is for patent No. CN106057433A, and in conjunction with Fig. 9~Figure 13, diagram selects from the patent.Magnetism member
Part includes a combined magnet core and the primary side winding on the combined magnet core, and each combined magnet core includes main magnetic core, one
A pair magnetic core and the vice-side winding being wound on the main magnetic core；Each primary side winding is wound on the main magnetic core of corresponding combined magnet core
