Pulse transformers
The TI series small-size pulse transformers
are constructed using high permeability
E / EF shaped ferrite cores and wound
using a special technique to achieve the
optimization of its inter-related electric
parameters, which determine the over-all
performance of the transformers. We shall
emphasize the following parameters:
- High galvanic insulation between primary
winding (control circuit) and secondary
winding (power circuit).
- Low coupling capacitance between
windings.
- Low stray inductance.
- High transfer capability of unipolar
pulses.
- Low losses in the magnetic circuit.
Applications:
Generally, they are used for triggering low,
medium and high power thyristors and
triacs, as well as for controlling power
transistors, used in power electronic
circuits.
The TI standard series consists of 16
encapsulated models in three case sizes
and with one or two secondary windings.
By request, we can manufacture special
models, according to customer
specifications, using other coil formers
and core shapes, sizes and types, with
some elec-trical features other than than
construction or encapsulated, using high
permeability E / EF shaped ferrite cores
or toroidal ones.
Features:
- Transfer area: from 200 to 700 V x µs
- Transformation ratio: 1:1, 1:1:1 and
3:1:1
- Trigger current: from 0.1 A to 1 A
- Dielectric strength: between 2.5 KVac
and 3.5 KVac (depending on the model)
- Size: (width x depth x height) in mm. (23
x 27 x 15), (23 x 16.5 x 25) and
(17 x 17.5 x 12).
