kW Converters

Application:
Transformers based on our 350 size core are designed
for a wide variety of topologies such as forward, half
and full
bridge, full bridge ZVS, and push-pull. These parts are
used in 2 kW to 6.0 kW off-line power supplies and DC-DC
converters
delivering up to 300 amperes for a single output or 20-50
amperes for multi-output magnetics. Applications are
industrial and military where small size, high quality,
reliability,
repeatability and superior thermal management are of
the utmost importance. For the power it is capable to deliver,
this is a very small and rugged package. A typical P350
transformer has a footprint that is smaller than a standard
credit card
and height from 0.800" to 1.100". Portable welding
equipment is one of many applications where P350 is very
suitable. Depending on the power rating, 350 size parts
can run without any air flow for cooling. In this case,
they
must be attached to a base plate with a controlled temperature.
Transformers operating close to a maximum of specified
power limit must be cooled by a combination of conduction
and air
flow. Custom transformers and inductors are available. |
