Encapsulated or Potted Coil, what to choose?
An electric coil is made up of two distinct parts: a conductor and a core. Typically, the conductor is solid copper wire wrapped around a metal core. A turn is formed by looping the wire …
Choosing an Optimal Number of Strands in a Litz-Wire Transformer Winding
A salient difficulty in designing high-frequency inductors and transformers is eddy-current effects in windings. These effects include skin-effect losses and proximity-effect losses. Both effects can be controlled by using Litz wire—conductors made up of multiple …
How does Diwali impact Manufacturing?
October and November are considered the busiest months in India. Clients speed up their decision-making during these months due to the approaching assortment of holidays, including Diwali. In this article, we shall elaborate more about …
Effects of Increasing Frequency on Transformers and Inductors
The operating frequency of many electronic circuits has been increasing since the late 1960s. The increase in frequency has decreased the size and weight of many consumer electronics available today. The frequency increase continues today, …
Primer for Flyback Transformers
Fundamentally, flyback transformers are step-up transformers but with massive potential of stepping up the voltage. For an input of 230V, a flyback transformer can achieve an output of up to 20,000V. Such is the potential …
In brief – Power autotransformers
Autotransformers are a special type of power transformers that feature a single winding wound onto a laminated core. They are used to either step up or step down the voltage. They’re similar to two-winding transformers. However, their …
Selecting the optimum cores for SMPS transformers
The selection of the magnetic components, especially transformer cores, to be used in a Switch Mode Power Supply (SMPS) design is the most crucial element. Core choice is generally based upon the application’s power requirements, …
Evaluating Insulation Integrity: Partial Discharge
One of the primary functions of a magnetic transformer is to provide isolation between two sections of an electronic circuit. This isolation is required to comply with a specific safety specification or protect sensitive circuits …
Choosing a Current or Potential Transformer
When measuring AC currents and voltages of high magnitude, we often take for granted clamp and amp meters. However, the question is, how are these portable measuring instruments able to step down the magnitude to …
Why are all transformer manufacturers not the same?
Transformers are the most critical element of almost all electrical systems, so choosing the most trusted, reliable, and experienced manufacturer becomes difficult. There are various transformer types available, each having a unique construction, a unique …
