High Frequency Switching Transformers

High Frequency Switching Transformers are typically used in electronic power applications to convert one DC input voltage to a different DC output voltage. The amount of power delivered can be controlled by varying the switching frequency and duty cycle of the switching transformer. There are a variety of circuit topologies that use switching transformers.  Flyback, Push-Pull, Forward Converter, Full-Bridge and Half-Bridge are popular topologies that CET can custom design for you!

Specialty Transformers

Our specialty transformers range from current sense and audio transformers to high voltage transformers.  Current sense transformers are typically designed to work with a one or two turn primary and a specific load resistance to obtain a fixed ratio of output voltage to primary current. Audio transformers (signal or impedance transformers) are designed to serve two purposes. First, they are used to transform circuit impedances. Second, because there is no electrical connection between primary and secondary, they provide isolation, which eliminates noise caused by ground loops.

High voltage transformers are usually used to convert a low voltage level to a much higher voltage level. They’re used in applications that require transformers to handle voltage levels of up to 15,000 volts safely and accurately. These transformers are most commonly used in industries like aerospace, automotive, energy, and manufacturing.
