Phase Transformers -> Inductors and Chokes
Carroll & Meynell design and manufacture to order
Single Phase AC Inductors
Three Phase AC Inductors
DC Chokes for operation with single phase systems.
DC Chokes for operation with three phase systems.
We build all inductive components to customers specific
requirements and can also offer design assistance and
recommendations for the application.
Typical applications include Line filters and Power
factor correction in the mains supply for AC inductors
and. DC chokes for ripple filtering components in battery
chargers and DC supplies.
The scope of supply for single phase AC and DC components
includes small units built on ‘EI’ laminations
with a gap between the ‘E’ block and ‘I’
block of the core.
Larger components are manufactured with dual coils
on ‘UI’ cores with the gap distributed through
the upright leg.
Three phase AC inductors have three coils built on
the legs of ‘3UI’ cores, smaller units being
pressed lamination patterns with a gap between to ‘3U’
block and the ‘I’ block of the core
Larger units being manufactured on cut strip lamination
with the gaps distributed in the upright legs
The size or rating of an inductive component is generally
determined by its inductance and the current it is designed
to carry according to
Rating = LI²
However other factors in the design can vary this generalization
most notably a requirement to control size of the gap.
For this reason size and weight data can only be supplied
in response to specific enquiries
Carroll & Meynell can build single phase items
up to approximately LI² = 1000 and three phase
inductors up to LI² = 2000
