Products High Frequency Transformers

High Frequency Transformers

’50kW at 50kHz, 100kW at 20kHz was said to be unrealistic in the field of high frequency transformers. ATL have been developing novel solutions and innovative manufacturing techniques to produce a wide range of high-power, high frequency transformers’

ATL with years of research has arrived at proprietary solutions for high power high frequency transformers and are proud to state that a number of customers are already benefiting from these solutions.

With the latest developments in power electronic components such as SiC MosFETs the demand for high power high frequency transformers has grown rapidly. Energy efficiency, low noise, reduced mass and dimensions have become more and more vital factors in designing magnetic’s for modern power electronic applications such as rolling stock and renewable energy applications.

In order to achieve a high degree of miniaturisation, power electronics designers move into significantly high operating (switching) frequencies in the development of modern high-power converters and inverters. This has made it challenging for many magnetic manufactures to supply compact high-power high frequency transformers.


ATL offer a family of high frequency transformers, low power transformers , high power high frequency transformers, high voltage high frequency transformers and Planar transformers for modern applications.

Power Range: 10W to 200kW     Input voltage:  50V to 1000V

Output voltage:  50V to 1000V  Frequency:  Up to 50kH in high power applications and up to 300kH in low power applications. 

Insulation classes: B(130), F(155)  and H(180)  operating within ambient temperatures:  -40 to +50 Degrees C.

In addition to open frame models we offer transformer solutions within our own unique and robust Industrial enclosures. We can service any IP rating requirements from standard indoor IP2X rating, IP5X Outdoor weatherproof applications and submersible solutions. Our swan neck type transformer housing introduced by ATL and now widely duplicated across industry provides a degree of cooling in these naturally cooled dry type transformers while maintaining superior levels of ingress protection.


Our In House Developed Programmes Delivery the Optimum Solution

Decades of experience developing magnetic’s to Industry manufacturing standards ensure that our products deliver high efficiency, long asset life, and ultimately zero failure rates.

ATL’s wealth of industry experience designing custom solutions has built a high level of knowledge used to create our own in house  highly sophisticated design programmes. These programmes give us flexibility within any design while giving customers an economically efficient tailored solution.

Utilisation of these programmes allows us to deliver the optimum design for our clients requirements delivering cost reductions and high levels of efficiency throughout the design.
