High Frequency Transformer for Rail
Shinenergy’s high-frequency transformer for rail could work at a high frequency of more than 16KHZ, widely applied in the rail traction system. It’s mainly applied to full bridge DC/DC converters.
- Wide operating frequency range from 16KHZ to 200KHZ
- Rated voltage: up to 25kV
- Power capacity is high up to 2800KVA
- CE, UL certificated
Customized Geometry Ferrite Core
Typically high frequency transformers use the ferrite core, different kinds of geometries of ferrite core are available, and whatever additional shielding or a specific form factor from clients, a ferrite core might meet the requirement.
Liz Wire Reduce the Loss
Shinenergy’s high-frequency transformer cooperated with Liz wire to reduce the skin effect, thereby reducing the loss, Litz wire is a multistrand wire, this wire is designed to reduce the skin effect, it’s constructed of many thin wire strands, and the size of each individual strand is determined by the intended working frequency.

Q1: What are the advantages of high-frequency transformers compared with typical types?
A1: Compared with typical transformers, high-frequency transformers with smaller sizes, have lower losses, and are more efficient.
Q2: What’s the application of the high-frequency transformer?
A2: High-frequency transformer could be applied for EV charging, railway, smart grids, renewable energy, etc.
Q3: What is critical when designing or choosing a high-frequency transformer?
A3: When choosing or designing a high-frequency transformer, how to minimize losses from skin effect, proximity effect, and how to choose the core material are critical.
Main Features of the High Frequency Transformer
High-frequency transformers operate at high frequencies from 16KHZ to over 1MHz, with the higher frequency, the transformer could be smaller, and the smaller size needs fewer wires, thereby reducing the losses and making the transformer more efficient, secondly, the core is typically ferrite, different kinds of geometries are available. Thirdly, the Litz wire could reduce the skin effect to reduce the losses.
