What is Frequency Response?

What is Frequency Response?

Brian Weston
Most of us know what frequency is; the high or low tones of sound. But some have asked what frequency response is and how it relates to transformers.
The Voltage Dilemma

The Voltage Dilemma

Brian Weston
Custom design a XPWR transformer with a number of outputs (secondaries) totaling 300VA. Let’s say one of the outputs is 6.3Vrms (all future comments will be rms Volts) at 5A. In addition, don’t let the temperature rise above 40 degrees Fahrenheit and keep the flux density well below saturation. Simple, right?
Design Overview

Design Overview

Brian Weston
Transformers are the least understood of all electrical components. So, we thought we would give you some insight into the design.
