IDT – Inverter Duty Transformer
Inverter Duty Transformers are used to convert direct current to alternate current. They are
used to get desired voltage levels when the output voltage is low but the desired voltage
is high.
Our range of IDT varies from 100 KVA to 18.5 MVA, the precise requirements vary from device to
device and from site to site. We offer Inverter Duty Transformers in ONAN and ONAF cooling.
We specifically design inverter duty transformer for Wind and Solar Energy applications
and provide them with multiple windings on the primary/secondary side of the transformer,
which enhances their performance by enabling them to connect multiple inverters to the
grid. We also provide Earth Shield between the HV and LV windings whose purpose is to
reduce harmonic and path to ground residual resonance. Special multiple windings design
on primary side of the transformer enables to connect multiple inverters to the grid with
minor number of transformers in total.
Special foil winding machines are used to make the primary and secondary coils of
the transformer, as the current in low voltage side if the transformer is high, foil winding
machines help to reduce the number of conductors the time of coil winding. Tap Leads
are designed across the axial length of the winding so that during short circuit the forces
will be distributed equally across the winding. Taps are used to adjust the turn’s ratio to
compensate for the variance in supply, thus increasing the transformer’s accuracy to
match the specified output.
