Detailed Description
The following description of the embodiments of the present invention is provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein.
As shown in fig. 2, the utility model discloses a staggered reverse coupling Boost-buck reactor comprises iron core 1, stem 2, winding 3, to inserting skeleton 4, stainless steel strip 5, the fixed buckle area 6 of temperature detect switch.
The core 1 includes a first core and a second core which are oppositely disposed, the first core and the second core form a reverse coupling inductive magnetic circuit (as shown in fig. 3, a magnetic flux part of a N1 winding enters a N2 winding, but the magnetic flux part generated by the N2 winding is opposite to that generated by a N2 winding (in the same way, the magnetic flux part generated by the N2 winding passes through the N1 winding and is opposite to that generated by the N1 winding), so that the saturation physical property of the inductor can be improved, the volume can be reduced, and the power density can be improved).
