Embodiment approach 1
[0024] use figure 1 and figure 2 , Embodiment 1 of the present invention will be described. figure 1 It is a plan view showing a schematic configuration of the transformer in the first embodiment. figure 2 It is a schematic diagram showing the schematic circuit of the transformer in Embodiment 1.
[0025] exist figure 1 and figure 2 Among them, the transformer 1 has a first core 2, a primary winding 3, a first connecting portion 4a, 4b, a secondary winding 5, a second connecting portion 6a, 6b, 6c, 6d, a tertiary winding 7 and a third connecting portion 8 . Here, the primary winding 3 is a winding wound around the first core 2 . The first connection parts 4a, 4b are connection parts for connecting the ends of the primary winding 3 to other circuits. The secondary winding 5 is a winding wound around the first core 2 . The second connection parts 6a, 6b, 6c, and 6d are connection parts for connecting the end part of the secondary winding 5 to another circuit. The ...
Embodiment approach 2
[0039] use figure 1 and figure 2 Embodiment 2 will be described. Embodiment 1 describes that by changing the number of turns of the tertiary winding 7 wound on the first core 2, the number of turns of the tertiary winding 7 wound on the second core 9, and the number of turns of the tertiary winding 7 wound on the second core 9, The turns ratio of the turns of the tertiary winding 7 on the iron core 9 and the turns of the tertiary winding 7 wound on the first iron core 2 and the material of the second iron core 9 can change the magnetic flux of the transformer 1. load characteristics.
[0040] However, in the case of supplying a load of magnetic flux from the second core 9 to the first core 2 through the tertiary winding 7 wound on the first core 2 and the second core 9 to form a closed loop, it is necessary to use The number of turns of the tertiary winding 7 wound on the first iron core 2 is smaller than the number of turns of the tertiary winding 7 wound on the second i...
Embodiment approach 3
[0044] use Figure 1 ~ Figure 3 , Embodiment 3 will be described. image 3 It is a graph showing the amount of heat generated by the second iron core 9 with respect to the turns ratio of the number of turns of the tertiary winding 7 wound on the second iron core 9 of the transformer 1 in Embodiment 3 of the present invention. and the turns ratio of the turns of the tertiary winding 7 wound on the first core 2 of the transformer 1 . image 3 The abscissa of is the turns ratio between the number of turns of the tertiary winding 7 wound on the second core 9 of the transformer 1 and the number of turns of the tertiary winding 7 wound on the first core 2 of the transformer 1 . image 3 The vertical axis of 1 represents: when the specified AC power is input from the first connection part 4a, 4b of the transformer 1 and the converted AC power is output from the second connection part 6a, 6b, 6c, 6d, the second iron The heating value of the surface of the core 9.
