EP Power Switchmode Transformers-Image

Switchmode Transformer designs are used extensively in high frequency electronic applications, usually within a switchmode power supply. Common transformer configurations include Flyback Transformers Design, High Frequency Transformers Design and Push-Pull Transformers Design. Precision Inc., a specialist in custom and standard magnetic design and manufacture, has been involved in developing Switchmode Transformers and other magnetic components for its' customers since 1964. During that time, Precision Inc. has customized many designs, specifically to our customer's specific need.

Precision Inc. has also developed "standard" switchmode transformers, Flyback Transformers and High Frequency Transformers using industry standard materials and footprints. These "standard" switchmode transformers are designed around a sizing factor. The sizing factor is a formula based upon the applications output power, topology (push-pull, bridge, full wave center tapped, forward, and flyback), and frequency. Using the estimated sizing factor an engineer can easily find which of the standard Precision Inc. families of Switchmode Transformers will work for his application.

Precision Inc. understands that each customer's SMPS Transformer Design requirement is unique. Our staff of design engineers works with our customers engineers to develop the best product for the application. Precision Inc. does not try to use a one size fits all mentality, and has developed new cores and mounting technologies for many of its customers.
