Abstract:
Coil of a transformer, the coil comprising a coil former made of an insulating material, the former comprising chambers along an axial line of the former, these chambers, delimited by radial partitions housing voltage step-up wire windings including a first winding, a last winding, and intermediate windings, each of these windings having two ends, an inner end and an outer end, each end of said windings being, with the exception of one of the ends of the first winding and of one of the ends of the last winding, connected to an end of a following or preceding winding or to an electrode of a step-up diode having two electrodes, an anode and a cathode, said coil comprising at least one pair of windings, the pair including two windings, a first winding of the pair and a second winding of the pair, housed in two consecutive chambers, at least a first diode and a second diode, the inner end of the first winding of the pair being connected to an electrode of the first diode, the inner end of the second winding of the pair being connected to the electrode of the second diode having a polarity the same as the electrode of the first diode connected to the inner end of the first winding.
