Efficient Compact 300VA Toroidal Power Transformer For Power
Conversion
1.Product performance:
Toroidal transformer is a large type of electronic transformer and
has been widely used in home appliances and other electronic
equipment with high technical requirements. Its main use is as a
power transformer and an isolation transformer. Toroidal
transformers have a complete series abroad and are widely used in
computers, medical equipment, telecommunications, instruments and
lighting. China's toroidal transformers have grown from nothing in
the past ten years, and have formed a considerable scale of
production so far. In addition to meeting China's domestic demand,
they are also exported in large quantities. China is mainly used in
audio equipment and automatic control equipment for home
appliances, as well as quartz lamp lighting and so on.
2.Application:
Such as for current and voltage transformers. High precision, high
stability transformer made by toroidal transformer process. New
high-performance magnetic materials such as permalloy soft magnetic
materials, amorphous materials or nanocrystalline alloys can be
used as magnetic cores, with precise intelligent instruments and
special testing methods. It can ensure accurate transformer
parameters and completely consistent performance.
3.Advantages of Toroidal Transformers:
1) The iron core with high electrical efficiency has no air gap,
the stacking coefficient can be as high as 95% or more, the
magnetic permeability of the core can be 1.5~1.8T (the laminated
core can only be 1.2~1.4T), the electrical efficiency can be as
high as 95% or more, no-load The current is only 10% of the
laminated type.
2) Small size and light weight Toroidal transformers can reduce the
weight by half compared to laminated transformers. As long as the
cross-sectional area of the core is kept equal, the toroidal
transformer can easily change the ratio of the length, width and
height of the core, and can be designed to meet the requirements.
3) The magnetic interference is small. The toroidal transformer
core has no air gap, and the windings are evenly wound on the
toroidal core. This structure leads to small magnetic flux leakage
and small electromagnetic radiation. High-sensitivity electronic
equipment can be used without additional shielding. , such as
low-level amplifiers and medical equipment.
4) Less vibration and noise, the iron core has no air gap, which
can reduce the iron core
