Wire winding require simpler, but be relatively adapted to wattage transformer or the low cost side lower slightly to reliability requirement
Case.
Third, this high pressure is divided into N number of low-voltage, it is superimposed after then N number of low-voltage is processed, it is possible to obtain phase
Same effect.
It will be seen that the common ground of first two scheme is output HIGH voltage, then go to process with circuit below.
3rd scheme is relatively reliable in technique, however, after being divided into N number of winding, lead-out wire also increases, so, between lead-out wire
Arcing, punch-through will increase.In order to increase the reliability of this scheme, arcing between coil, punch-through are reduced, this
Accomplish the method for enough insulation distances between a kind of coil of invention research in less space.
