High-frequency transformers aren’t a new concept. In-fact they have been a staple in radio frequency circuits, amplifiers, antennas, and transmitters. However, in today’s high-tech world of internet-connected mobile devices, renewable energy, and electric vehicles, the need for high-frequency transformers has grown exponentially over the past decade. Unlike low-frequency transformers, they come with additional design considerations.

In your typical line-level transformer operating at 60hz (low frequency), it will generally use a laminated iron core as the waveform has no problem saturating through. However, as the frequency is increased, an iron core will start to experience an increase in hysteresis losses, also known as the “rubbing effect.” Essentially, the “faster” you magnetize and demagnetize an iron core, the more heat is generated, which at a certain point becomes incredibly inefficient – this is where a different material such as a ferrite core begins to make sense. Ferrite losses are significantly less; however, it comes with a tradeoff. Ferrite cores offer less mechanical strength and become more brittle the larger they become. Therefore, the type of application, as well as the power levels required, will ultimately determine whether or not a ferrite core is viable.

The good news is there are several other advanced materials other than ferrites that can be used as an alternative, but they too have their unique tradeoffs. That being said, there is no one-size-fits-all approach when it comes to high-frequency transformers – this is where our expertise comes into play. Our engineers have been designing high-frequency transformers for decades and know how to design a product that is efficient and highly reliable. In-fact, our high-frequency designs are used in mission-critical military and aerospace applications. The next time you are in need of a complex transformer, start with Pacific Transformer.

When it comes to quality, some come close to our high standards but no one can beat us. We have spent decades devising a quality management system that ensures the highest standards possible. These quality standards have been independently audited and certified by the most demanding auditors and agencies. Organizations such as ISO, the International Aerospace Group and NSF International. We are also qualified by UL, CSA, ETL and TUV. We have over one million of our products on various military apparatuses. Medical equipment, satellites, railroad safety and traffic control all require the highest level of quality because there simply can be no failure.
