Designing A Transformer - Part 2: Designing a Single-Phase Power Transformer

Designing A Transformer - Part 2: Designing a Single-Phase Power Transformer

Brian Weston
Single-phase power transformers are the backbone of electronics. In this section, we will delve into the math of the design process by calculating voltages, currents, turns for each winding, choosing core material and determining magnet wire sizes.

Designing A Transformer - Part 1: The Basics

Brian Weston
This is Part 1 of a multi-part blog series that will cover the basics of transformer design. Part 1 of this blog series covers the basic transformer theory, parts of a transformer, and transformer schematic.
The Making of an EDCOR Transformer.

The Making of an EDCOR Transformer.

Brian Weston
The production process for manufacturing EDCOR transformers has developed over four decades. We often get calls inquiring about the status of a tra...
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.
Tri-Tone Generator

Tri-Tone Generator

Brian Weston
This little circuit is a 3 tone generator. Back in the late 1970's and 1980's EDCOR used this generator on the a number of input modules that were used in their modular power and mixer amplifier. This module would supply a tri-tone to the amplifier when a set of connection was complete. It was use security and notification across the background sound system.
