PQ3230 High-Frequency Transformer Manufacturer Customized DW4090
High-frequency transformers operate using the same basic principles
as standard transformers. The primary difference is that, as their
name implies, they operate at much higher frequencies — while most
line voltage transformers operate at 50 or 60 Hz, high-frequency
transformers use frequencies from 20 KHz to over 1MHz.Operating at
a higher frequency has many benefits, the first of which is
size.For any given power rating, the higher the frequency, the
smaller the transformer can be.
