Transformers are very versatile for electronics applications and can be used in many ways. So believes Robin Evans, the Senior Design and Development Engineer at Wound Magnetics. He provides the introduction to the latest addition to our Trends & Technologies section: an Electronics Weekly guide to transformers.
Devices will generally fall into one of four electrical/magnetic categories, he notes - power, signal, pulse and inductive - before outlining that an optimum design requires all the important parameters to be defined.
An optimum design requires all the important parameters to be defined, and the designers need a full understanding of the application and an awareness of any test voltages. In addition to a complete performance specification, a circuit description and diagram is also very useful. The various trade-offs can then be fully investigated.Pertinent parameters will depend on the application, but there will always be a need for details of the working environment, the available cooling and whether there is temperature rise limit. Any size and weight constraints will be considered together with preferred mounting and termination methods.
