Medium Frequency Transformers for Induction Heating & Power Supplies

Medium Frequency Transformers are based on electromagnetic induction and provide voltage conversion, isolation, and impedance matching, the same way as all transformers. Medium Frequency Transformers operate in the medium frequency range whereas low-frequency transformers were primarily intended for the low frequency range (up to 50Hz). Medium Frequency Transformers fill the void created by the demand for both methods of transferring power, high frequency and low frequency. Medium Frequency Transformers have numerous applications because the medium frequency range delivers the highest efficiency in transferring energy with the lowest amount of energy loss and highest activity/increased performance. Therefore, Medium Frequency Transformers also lend themselves extremely well to products and applications that require a smaller size and weight compared to conventional transformers and still maintain the same or greater power handling capabilities than regular transformers.

The construction of a Medium Frequency Transformer reflects engineering excellence through its laminated iron core and copper winding assembly that enhance the magnetic properties of the transformer and reduce eddy current losses of the transformer, a common problem associated with the higher operating frequencies. Additionally, insulation within the transformer protects against dielectric failure and preserves the operational integrity of the transformer at all times and provides cooling capability during continuous operation allowing for operation on a continuous basis, therefore, providing many applications for reliable and stable power conversion through the use of a Medium Frequency Transformer.

Five to ten percent of electricity used commercially and industrially in regions serviced by many of the same utilities that provide electricity for homes and businesses comes from renewable energy sources. These locations also have relatively favorable climate conditions for solar or wind generation. One area of tremendous growth potential is in the automotive industry; medium frequency transformers are now being employed to help improve the performance of electric vehicles. The medium frequency transformer's ability to optimize power distribution from the battery pack to the electric motor not only increases the overall efficiency of the electric vehicle's energy consumption, it helps increase the vehicle's range.

Thus, it can be reasonably concluded that the medium frequency transformer is far more than just an energy conversion device—it is a key driver of power engineering innovation. Its unique ability to efficiently transmit electrical energy at midrange frequencies provides many benefits to manufacturers and end users of new electric vehicles. As the automotive industry continues to push the envelope on what is possible with new electric vehicle technologies, the medium frequency transformer will continue to play an integral role in both current and future designs. By investing in technology that includes the use of medium frequency transformers will allow utilities to benefit from increased performance, improved efficiencies, and increased reliability with all of their energy solutions.
